Abstract

Abstract Photolysis of a series of E or Z stereoisomeric α-R-substituted bromostyrenes (R= CH 3, F or CN) in methanol yields E and/or Z stereoisomeric styrenes, which stem from the corresponding vinyl radicals. The results show that the α-Me vinyl radical is a rapidly equilibrating, bent structure, while the α-F vinyl radical is a stable bent species, in agreement with earlier thermal results. The α-CN vinyl radical is assigned as a rapidly inverting bent ...
