Synthesis of efficient and reusable catalyst was carried out by immobilization of azacrown ether onto the covalently linked amine-functionalized mesoporous MCM-41 via a simple method. Application of this linked azacrown ether functionalized MCM-41 catalyst was also investigated as an effective, heterogeneous and host material in the regioselective ring opening and triazole cyclization of epoxides by phenylacetylene and sodium azide in click reaction. The heterogeneous catalyst was characterized by TGA,XRD,TEM, ¹HNMR, ¹³CNMR and FT-IR techniques. The results of theses anal. showed that, MCM-41@azacrown-Cu with a 22.99% mol loading of copper has given excellent catalytic activity and high efficiency in short time. It is noted that one of the most valuable factors in this work is the recyclability of the catalyst.

Karasu, Feyza published the artcilePhotoinitiated polymerization of β-cyclodextrin/methyl methacrylate host/guest complex in the presence of water soluble photoinitiator, thioxanthone-catechol-O,O’-diacetic acid, HPLC of Formula: 5411-14-3, the publication is Journal of Inclusion Phenomena and Macrocyclic Chemistry (2010), 68(1-2), 147-153, database is CAplus.

β-Cyclodextrin (β-CD) was used to complex the monomer, Me methacrylate (MMA), yielding a water-soluble host/guest complex. Photoinitiated polymerization of β-CD/MMA complex was achieved in the presence of thioxanthone-catechol-O,O’-diacetic acid (TX-Ct), a one component water soluble photoinitiator. Photodecarboxylation of TX-Ct in water seems to be an important reaction mechanism. Therefore, resulting alkyl radicals are able to initiate the polymerization of β-CD/MMA host/guest complex in water.

Thuery, Pierre published the artcileFunctionalized Aromatic Dicarboxylate Ligands in Uranyl-Organic Assemblies: The Cases of Carboxycinnamate and 1,2-/1,3-Phenylenedioxydiacetate, Computed Properties of 5411-14-3, the publication is Inorganic Chemistry (2020), 59(5), 2923-2936, database is CAplus and MEDLINE.

2-Carboxycinnamic acid (ccnH₂) and the isomeric 1,2- and 1,3-phenylenedioxydiacetic acids (1,2- and 1,3-pddaH₂) have been used to synthesize eight uranyl ion complexes under solvo-hydrothermal conditions. In the four complexes [PPh₄]₂[UO₂(ccn)(NO₃)]₂ (1), [PPh₄]₂[UO₂(ccn)(dibf)]₂ (2), [UO₂(ccn)(bipy)]₂ (3), and [Ni(R,S-Me₆cyclam)][UO₂(ccn)(HCOO)]₂ (4), the ccn^2- dianion retains a nearly planar geometry, which favors the formation of the centrosym. [UO₂(ccn)]₂ dimeric unit. Addnl. terminal ligands, either neutral (bipy = 2,2′-bipyridine) or anionic (nitrate, dibf^– = 1,3-dihydro-3-oxo-1-isobenzofuranacetate, and formate, the two latter formed in situ), complete the uranyl coordination sphere, leading in all cases to discrete, dinuclear species. Sodium(I) bonding to the carboxylate/ether O₄ site of the 1,2-pdda^2- dianion in the two complexes [UO₂Na(1,2-pdda)(OH)] (5) and [(UO₂)₂Na₂(1,2-pdda)₂(C₂O₄)] (6) results in this ligand being planar. Further lateral coordination to uranyl and sodium bonding to a uranyl oxo group allow formation of heterometallic diperiodic networks containing monoperiodic uranyl-only subunits. In the absence of Na⁺ cations, 1,2-pdda^2- adopts a conformation in which one carboxylate group is tilted out of the ligand plane in [UO₂(1,2-pdda)₂Ni(cyclam)] (7) and diaxial carboxylato bonding to nickel(II) unites uranyl-only monoperiodic subunits into a diperiodic network. The 1,3-pdda^2- ligand in [UO₂(1,3-pdda)(H₂O)] (8) is also nonplanar with one tilted carboxylate group, and the bridging bidentate nature of both carboxylate groups allows formation of a triperiodic framework in which both metal and ligand are four-coordinated nodes. While the emission spectra of complexes 1 and 5 display the vibronic progression considered typical of uranyl ion, those of complexes 2, 4, and 8 show broad emission bands which in the case of complex 4 completely replace the uranyl emission and which appear to be ligand-centered. The low energy of these broad bands can be rationalized in terms of the close association of certain ligand pairs within the structures. 2-Carboxycinnamate is a ligand with a marked tendency to planarity, which, in the presence of terminal coligands, consistently forms quasi-planar, dinuclear, dimeric units with the uranyl ion. In contrast, the isomeric 1,2- and 1,3-phenylenedioxydiacetates can adopt either planar or nonplanar conformations, leading to various di- and triperiodic assemblies.

Karasu, Feyza published the artcileMechanistic Studies of Photoinitiated Free Radical Polymerization Using a Bifunctional Thioxanthone Acetic Acid Derivative as Photoinitiator, HPLC of Formula: 5411-14-3, the publication is Macromolecules (Washington, DC, United States) (2009), 42(19), 7318-7323, database is CAplus.

A bifunctional photoinitiator for free radical polymerization, thioxanthone catechol-O,O’-diacetic acid, was synthesized, characterized, and compared to photoinitiator parameters of the monofunctional analog, 2-(carboxymethoxy)thioxanthone. Photophys. studies such as fluorescence, phosphorescence, and laser flash photolysis in addition to photopolymerizations of Me methacrylate show that the bifunctional photoinitiator is more efficient in polymer generation than the monofunctional derivative These studies suggest that initiator radicals are generated from a π-π* triplet state in an intramol. electron transfer, followed by proton transfer and decarboxylation to generate alkyl radicals, which initiate polymerization The initial electron transfer is faster for the bifunctional photoinitiator than the monofunctional derivative, which is based on laser flash photolysis studies. Because of the relatively fast intramol. radical generation from the triplet state (triplet lifetime = 490 ns), quenching by mol. oxygen is insignificant and polymerization of Me methacrylate proceeds efficiently without deoxygenation. At higher concentrations of initiator (âˆ? mM) intermol. electron transfer competes with intramol. electron transfer. Both processes, inter- and intramol. processes, yield initiating alkyl radicals.

The title amides (I; R, R¹ = H, alkyl, aryl, cycloalkyl, NRR¹ = heterocycle containing optional O atom, etc.) were prepared I selectively chelated Group IIA cations by picrate extraction from water to CH₂Cl₂. This result was also confirmed by at. absorption measurement. The changes in UV absorption of aromatic rings and amide groups in the ligands upon titration with metal salts in methanol allowed an estimation of the ordering of cation binding.
