We report herein a simple synthesis of 4-styryldiphenylphosphine and the radical copolymerization of it with styrene, both with and without a cross-linker, to directly form cross-linked and non-cross-linked polystyrene supported triphenylphosphine in which the level of phosphine incorporation can be easily and accurately controlled. The utility of these polymers is demonstrated by their use in Mitsunobu and alcohol bromination reactions.
Carboxylic acid estersCarboxylic acid esters Q 0530 Direct Radical Polymerization of 4-Styryldiphenylphosphine: Preparation of Cross-Linked and Non-Cross-Linked Triphenylphosphine-Containing Polystyrene Polymers. -A facile route to the phosphine (III) is reported. It smoothly undergoes copolymerization with styrene in the presence and absence of a cross-linker. The resulting phosphine-containing polymers are able to promote Mitsunobu reaction as well as bromination of alcohols. -(CHOI, M. K. W.; HE, H. S.; TOY*, P. H.; J. Org.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
