Monomeric and polymeric phenothiazine photosensitizers for photoinitiated cationic polymerization
Gomurashvili, Zaza,Crivello, James V.
, p. 2962 - 2969 (2002)
The syntheses of several phenothiazine compounds bearing cationically polymerizable vinyl, vinyl ether and epoxide groups are described. These monomers were rapidly and efficiently polymerized or copolymerized by UV irradiation in the presence of onium salt photoinitiators. In addition, the monomers simultaneously function as efficient photosensitizers for the photolysis of the onium salts. In this article, the use of these polymerizable photosensitizers for the photopolymerizations of epoxide and vinyl ether monomers is reported. The inclusion of a small amount of the monomeric photosensitizer is effective in markedly accelerating the cationic photopolymerization of the bulk monomer. Polymers prepared by the polymerization of the monomeric phenothiazine photosensitizers also exhibit excellent photosensitization activity when used in combination with diaryliodonium, triarylsulfonium, and dialkylphenacylsulfonium salt photoinitiators.

The activation of C-O bonds in allylic acetates in water as a suspension medium has been accelerated by carrying out the reactions in the presence of platinum complexes associated with ligands. The platinum-catalyzed allylation of aminonaphthalenes using allylic acetates gave the corresponding N-allylic aminonaphthalenes in good yields.

The activation of C-O bonds in allylic acetates has been accelerated by carrying out the reactions in the presence of platinum complexes associated with ligands. Platinum-catalyzed allylation of aminonaphthalenes with allylic acetates leads to N-allylic aminonaphthalenes in good yields.
Palladium-catalyzed allylation of acidic and less nucleophilic anilines using allylic alcohols directly
Hsu, Yi-Chun,Gan, Kim-Hong,Yang, Shyh-Chyun
, p. 1266 - 1269 (2007/10/03)
The direct activation of C-O bonds in allylic alcohols by palladium complexes has been accelerated by carrying out the reactions in the presence of titanium(IV) isoproxide and 4 A molecular sieves. The acidic and less nucleophilic anilines such as diphenylamine, phenothiazine, 4-cyanoaniline, and nitroanilines are efficiently allylated under palladium catalysis using allylic alcohols as allylating reagents.
One-pot synthesis of pharmacologically active diamines via rhodium- catalysed carbonylative hydroaminomethylation of heterocyclic allylic amines
Rische, Thorsten,Mueller, Kai-Sven,Eilbracht, Peter
, p. 9801 - 9816 (2007/10/03)
Pharmacologically active derivatives of phenothiazine, iminodibenzyl, carbazole and pyrazole are prepared with high yields and chemoselectivity by the reaction of the corresponding N-allylic or N-methallylic compounds, primary or secondary amines, carbon monoxide and hydrogen in the presence of [Rh(cod)Cl]2 as catalyst via a one pot hydroformylation - amine condensation - reduction sequence.
