The four isomers of chloroepoxypropane have been prepared, and their relative reactivities with triphenyltin hydride have been determined. The three a-chloroepoxypropanes react at a much slower rate than does epichlorohydrin, the only Fchloro epoxide of the four. The nature of the increased reactivity for the f?-chloro epoxidea has been investigated by studying two pair of diastereomeric@-chloro epoxides, and a single acyclic f?-chloro ether. The results ...
