Sibi, Mukund P. published the artcileNitrogen-15 nuclear magnetic resonance spectroscopy. Natural-abundance nitrogen-15 chemical shifts of ring-methylated N,N-dimethylanilines. Effect of inhibition of conjugation, Safety of 2,6-Diisopropyl-N,N-dimethylaniline, the publication is Journal of Organic Chemistry (1977), 42(18), 2999-3004, database is CAplus.

The 15N chem. shifts of PhNHMe, PhNMe2 (I), several ring-alkylated derivatives of I, and their conjugate acids were determined at the natural abundance level. Relative to aniline, N-methylation induced upfield shifts, in contrast to the downfield shifts expected on ¦Á-substitution. The influence of ring-Me substitution on the resonance position of PhNMe2 was the same as that reported for aniline, except for o-substitution. Under these conditions, considerably larger upfield shifts were observed In contrast, the chem. shifts of the conjugate acids all lay within a 2-ppm range. The large diamagnetic shifts induced by o-Me substitution were attributed to the torsional distortion of the MeN group from the optimum conformation for N lone-pair delocalization. The results correlated with appropriate aniline 13C chem. shifts. and, especially, with the ionization potentials of the corresponding aniline ¦Ð orbitals, which are a measure of N lone-pair ¦Ð delocalization. The diamagnetic ¦Á effects could also be rationalized by this means. The N shifts of 2,6-diethyl- and 2,6-diisopropyl-N,N-dimethylaniline were used to estimate torsional angles of 77 and 80¡ã, resp.

Strandwitz, Nicholas C. published the artcileOne- and Two-Photon Induced Polymerization of Methylmethacrylate Using Colloidal CdS Semiconductor Quantum Dots, Recommanded Product: 2,6-Diisopropyl-N,N-dimethylaniline, the publication is Journal of the American Chemical Society (2008), 130(26), 8280-8288, database is CAplus and MEDLINE.

The development of one- and two-photon induced polymerization using CdS semiconductor quantum dots (QDs) and amine co-initiators to promote radical generation and subsequent polymerization is presented. Two-photon absorption (TPA) cross-section measurements, linear absorption, and transmission electron microscopy are used to characterize the QDs. The effectiveness of the co-initiators in increasing the efficiency of photopolymerization (polymer chains formed per excitation) is examined Triethylamine was observed to be most effective, yielding quantum efficiencies of initiation of >5%. The interactions between the co-initiators and QDs are investigated with steady-state photoluminescence and IR spectroscopies. Possible initiation mechanisms are discussed and supported by electrochem. data. Making use of the surface chem. developed here and the large QD TPA cross-sections, two-photon induced polymerization is demonstrated. The large TPA cross-sections coupled with modest quantum efficiencies for initiation reveal the unique potential of molecularly passivated QDs as efficient two-photon photosensitizers for polymerization

An I₂-CF₃SO₃H synergistic promoted sp³ C-H bond diarylation protocol was developed for the synthesis of 2,2-bis(4-(dimethylamino)phenyl)-1-aryl ethanones. Thus, reacting R¹COMe (R¹ = Ph, 4-MeOC₆H₄, 2-thienyl, etc.) with R²C₆H₅ (R² = NMe₂, NEt₂, NPr₂, etc.) in the presence of I₂/CF₃SO₃H/DMSO gave diarylketones I. The reaction performed well in the absence of any metal and ligand. It integrated three reactions with different mechanisms (iodination, Kornblum oxidation, and hydroarylation) in a single reactor.

Lu, Youmei published the artcileHighly efficient two-photon initiated polymerization in solvent by using a novel two-photon chromophore and co-initiators, Safety of 2,6-Diisopropyl-N,N-dimethylaniline, the publication is Journal of Materials Chemistry (2004), 14(9), 1391-1395, database is CAplus.

Highly efficient two-photon initiated polymerization (TPIP) of acrylate monomer in dioxane solution was carried out using three-component photoinitiator system containing a novel D-¦Ð-A-¦Ð-D type chromophore I (Ia; R = Bu₂N, Ib; R = Et₂N), the co-initiator 6-diisopropyl-N,N-dimethylaniline (DDA) and diphenyliodonium salt, Ph₂I⁺PF₆^–(PIP). The authors measured the quasi two-photon polymerization rates (R_p) based on scanning speed and the width of the written protruding line. Polymerization rates of in the presence of chromophore Ia and Ib were 113 ¦Ìm³ s^-1 and 157 ¦Ìm³ s^-1 in the case of the laser power 4.5 mW at 820 nm (pulse width: 85 fs, repetition rate 82 MHz ) resp. In order to estimate the mechanism of the photochem. reaction, the change of UV absorption of the three-component system, T-T transient absorption and the cyclic voltammetry (CV) of the novel chromophores were measured. The authors concluded that highly efficient electron transfer between DDA and the chromophore contributed to the long-lived radical cations of the chromophore. As a result, the generation of both DDA radicals and Ph radicals was ascribed to high sensitivity in TPIP.

In this article authors discuss a single Ru complex that is able to convert carbon dioxide and amines into various kinds of N-methylated products. The initial design was motivated by previous reports on the dehydration of primary amides using silanes and the hydrosilylation of carboxylic acid derivatives by us and other groups. Hence, the reaction of carbon dioxide and N-methylaniline in the presence of silanes as a model system was investigated. To identify active catalysts different metal precursors including Ru, Rh, Cu and Fe complexes and phosphine and nitrogen ligands were tested using phenylsilane as reductant.

Fitilis, I. published the artcileTwo-photon polymerization of a diacrylate using fluorene photoinitiators-sensitizers, Synthetic Route of 2909-77-5, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2010), 215(1), 25-30, database is CAplus.

Two-photon polymerization (TPP) of a diacrylate (monomer) using 2 different fluorene mols. as photoinitiators-sensitizers is reported. The fluorene mols. contain e^– donating (triphenylamine) or e^– withdrawing (phthalimide) edge substituents. An amine co-initiator is also used lowering the polymerization threshold. The dependence of the polymerization properties (threshold, polymerization rate, lateral and axial resolution) on the type of resin, the writing power and speed as well as on the NA of the focusing lens is studied. The fluorene with triphenylamine substituent exhibits favorable properties as TPP photoinitiator-sensitizer compared to the fluorene with phthalimide, although its 2-photon absorption cross-section is smaller. Polymerization of the pure monomer or monomer-amine composite (i.e. without fluorene) is also reported.

A new photochem. approach for free radical polymerization has been developed. The system releases trialkylborane from its complex with 4-(dimethylamino)pyridine upon irradiation The presence of a free borane in the formulation, when it encounters oxygen, promotes radical polymerization The system, when irradiated by an ergonomic 395 nm LED array, is able to efficiently overcome surface oxygen inhibition. The properties of the resulting photopolymer surfaces either matched or exceeded those of controls polymerized under N₂ atmosphere or with high-intensity light source. Results of exptl. and computational studies probing the mechanism of borane photorelease are also discussed. Safety consideration, all reagents and reaction mixture in synthesis af amine-borane complexes should be kept under dry Ar atm. since triethylborane is pyrophoric.

Howell, Barbara F. published the artcilePigmented coatings cured with visible light, HPLC of Formula: 2909-77-5, the publication is ACS Symposium Series (1997), 219-232, database is CAplus.

Use of photobleaching photoinitiators in an environmentally friendly, visible light curable, pigmented coating which can be applied for touch up purposes to minimally prepared steel surfaces, was studied. Addnl. requirements are that the coating does not yellow during aging and that it can be applied to a cold surface. Photoinitiators containing BAPO [bis(2,6-dimethoxybenzoyl)-2,4,4-trimethylpentyl-phosphine oxide] and DIBF (5,7-diiodo-3-butoxy-6-fluorone) were tested. DIBF can initiate curing by free radical reactions and by cationic means. DIBF is used with an amine and the cationic photoinitiator OPPI (4-octyloxyphenylphenyl-iodonium hexafluoroantimonate) for radical initiation, but for cationic initiation only OPPI and DIBF are needed. Resins used were: Ebecryl 3700 epoxy acrylate, Unicarb, and Heloxy 505 modifier; monomers were: isobornyl acrylate, trimethylol propane triacrylate, tripropylene glycol trimethacrylate, Photomer 4017 [1,6-hexanediol diacrylate], and Epon 828. Addnl. photoinitiators used were: Darocur 1173, Darocur 4265, Irgacure 907, CGI 1700, FX-512, H-Nu 470, and DIDMA [N,N-dimethyl-2,6-diisopropylaniline]. The photosensitizer used was ITX [isopropylthioxanthone] and the pigments include TiONa, TiO₂, Lampblack, manganese ferrite, and copper chromite. A cycloaliphatic epoxy coating formulation, was rapidly cured cationically with OPPI and DIBF and only a small amount (0.1%) of DIBF photoinitiator was required, to achieve through cure. The use of borate photoinitiators with DIBF, OPPI, and DIDMA was also studied.
