A series of cis and trans allylic halides has been reduced with triphenyltin hydride in a chain reaction which involves allylic radicals. Varying degrees of cis-trans isomerization of the intermediate allylic radicals have been observed and it has been shown that the variation is concentration dependent and also dependent on structure. Attempts to study allylic radicals where there is delocalization of the free electron onto CN, C02CH3, and CON (CH& by the ...
