Cakmakci, Emrah published the artcileFlame retardant thiol-ene photocured coatings, Related Products of catalysis-chemistry, the publication is Reactive & Functional Polymers (2011), 71(1), 36-41, database is CAplus.

The low polymerization tendency of allyl compounds can be enhanced by thiol-ene polymerization systems. In this study, allyldiphenyl phosphine oxide (ADPPO) containing thiol-ene based photocured coatings were prepared with the aim to improve their final thermal and flame retardant properties. The photopolymerization kinetics of thiol-ene based formulations were investigated by real-time IR spectroscopy. The incorporation of ADPPO into the polymer chains was confirmed by monitoring the conversion of acrylate double bonds and measuring the gel content of the crosslinked films. The experiments showed that as the amount of ADPPO was increased, thermal and flame retardant properties of the coatings were also increased.

Roversi, Elena published the artcileSubstituent effect on the competition between hetero-Diels-Alder and cheletropic additions of sulfur dioxide to 1-substituted 1,3-butadienes, Safety of Allyldiphenylphosphine oxide, the publication is Helvetica Chimica Acta (2002), 85(3), 733-740, database is CAplus.

The reactivity of sulfur dioxide toward variously substituted butadienes was explored in an effort to define the factors affecting the competition between the hetero-Diels-Alder and cheletropic additions At low temperature (<-70¡ã), 1-alkyl-substituted 1,3-dienes that can adopt s-cis-conformations add to SO₂ in the hetero-Diels-Alder mode in the presence of CF₃COOH as promoter. In the case of (E)-1-ethylidene-2-methylidenecyclohexane, the [4+2] cycloaddition of SO₂ is fast at -90¡ã without acid catalyst. (E)-1-(Acyloxy)-1,3-butadienes also undergo the hetero-Diels-Alder addition with SO₂+CF₃COOH at low temperatures, giving a 1:10 mixture of the corresponding cis- and trans-6-(acyloxy)sultines. Above -50¡ã, the sultines undergo complete cycloreversion to the corresponding dienes and SO₂, which that add in the cheletropic mode at higher temperature to give the corresponding 2-substituted sulfolenes. The hetero-Diels-Alder additions of SO₂ follow the Alder endo rule, giving first the 6-substituted cis-sultines that equilibrate then with the more stable trans-isomers. This statement is based on the assumption that the S=O group in the sultine prefers a pseudo-axial rather than a pseudo-equatorial position, as predicted by quantum calculations The most striking observation is that electron-rich dienes , such as 1-cyclopropyl-1,3-butadiene, 1-phenyl-1,3-butadiene, 1-(4-methoxyphenyl)-1,3-butadiene, 1-(trimethylsilyl)-1,3-butadiene, 1-phenoxy-1,3-butadiene, 1-(4-chlorophenoxy)-1,3-butadiene, 1-(4-methoxyphenoxy)-1,3-butadiene, 1-(4-nitrophenoxy)-1,3-butadiene, 1-(2-naphthalenyloxy)-1,3-butadiene, 1-(methylthio)-1,3-butadiene, 1-(phenylthio)-1,3-butadiene, 1-[(4-chlorophenyl)thio]-1,3-butadiene, 1-[(4-methoxyphenyl)thio]-1,3-butadiene 1-[(4-nitrophenyl)thio]-1,3-butadiene, and 1-(phenyl-seleno)-1-1,3-butadiene, as well as 1-(methoxymethylene)-2-methylenecyclohexane do not equilibrate with the corresponding sultines between -100¡ã and -10¡ã in the presence of large excess of SO₂, with or without acidic promotor. The hetero-Diels-Alder additions of SO₂ to 1-substituted (E)-1,3-butadienes are highly regioselective, giving exclusively the corresponding 6-substituted sultines. The 1-substituted (Z)-1,3-butadienes do not undergo the hetero-Diels-Alder additions with sulfur dioxide.

Imamoto, Tsuneo published the artcileReduction of organic compounds with rare-earth intermetallics containing absorbed hydrogen, Product Details of C15H15OP, the publication is Journal of Organic Chemistry (1987), 52(26), 5695-9, database is CAplus.

The hydrogenation of organic compounds with rare-earth intermetallic hydrides has been investigated. Alkynes, alkenes, aldehydes, ketones, nitriles, imines, and nitro compounds are hydrogenated in excellent yields with LaNi₅H₆ or LaNi_4.5Al_0.5H₅ at 0-60¡ã. The present hydrogenation method has the following characteristic features: (1) The intermetallic compounds (alloys) are not poisoned by compounds containing an amino group or a halogen atom. (2) The alloys can be used repeatedly without decrease in activity. (3) The reaction conditions are mild, and selective hydrogenations of some organic functional groups can be achieved. The reaction mechanism of this hydrogenation is briefly discussed in terms of stereochem. and H/D exchange reactions.

Galico, Diogo Alves published the artcileA highly sensitive luminescent ratiometric thermometer based on europium(III) and terbium(III) benzoylacetonate complexes chemically bonded to ethyldiphenylphosphine oxide functionalized polydimethylsiloxane, HPLC of Formula: 4141-48-4, the publication is New Journal of Chemistry (2018), 42(23), 18541-18549, database is CAplus.

This work reports on a ratiometric optical temperature probe consisting of a pdms-eddpo(1%)-[Tb_0.90Eu_0.10(bzac)₃](0.25%) membrane where lanthanide(III) complexes are chem. bonded to ethyldiphenylphosphine oxide functionalized polydimethylsiloxane. The ratiometric luminescent temperature probe shows a maximum relative thermal sensitivity of 11.05% K^-1 at 203 K, being one of the most sensitive lanthanide systems reported so far. Besides that, the operational range of the ratiometric probe is 158-248 K, where few systems have high sensitivity. Energy transfer is evident from terbium(III) to europium(III) contributing to the high relative thermal sensitivity of the systems. The optical probe is reversible showing a temperature uncertainty smaller than 0.08 K in the operational range.

Chardon, Aurelien published the artcileMetal-free reduction of phosphine oxides, sulfoxides, and N-oxides with hydrosilanes using a borinic acid precatalyst, Category: catalysis-chemistry, the publication is ChemCatChem (2017), 9(24), 4460-4464, database is CAplus.

The general reduction of phosphine oxides, sulfoxides, and amine N-oxides was achieved by combining bis(2-chlorophenyl)borinic acid with phenylsilane. The reaction was shown to tolerate a wide range of substrates and could be performed under mild conditions, with only 2.5 mol% of the easily synthesized catalyst. Mechanistic investigations pointed to a key borohydride as the real catalyst and at bis(2-chlorophenyl)borinic acid as a precatalyst.
