- Preparation of poly(vinylbenzyltriphenylphosphonium perbromide) and its application in the bromination of organic compounds. Akelah, A.; Hassanein, M.; Abdel-Galil, F. (Fac. Sci. 19967-57-8 and 5952-71-6 are cas registry numbers. These chemicals are also mentioned in this article., Tanta Univ., Tanta, Egypt). Eur. Polym. J., 20(3), 221-3 (English) 1984. CODEN: EUPJAG. ISSN: 0014-3057. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 21 Insol. poly(vinylbenzyltriphenylphosphonium perbromide) (I) was prepd. by treating 2% crosslinked poly(p-bromomethylstyrene) with PPh3 and Br. The activity of I was compared with that of the monomeric analog in the direct brominations of alkenes and carbonyl compds. In addn. to 75-92% yields of the brominated products and the ease and simplicity of the method, the resulting polymeric by-product could be treated to regenerate I without loss of activity. .
