Preparation and Identification of cis and trans Isomers of a Substituted Triarylethylene

Abstract

WE have prepared a series of l-(p-dialkylamino alkoxyphenyl) 2 alkyl-1,2-diphenylethylenes1 and in many instances have isolated the respective isomers2. The differences in biological activity of one pair of cis and trans isomers, I.C.I, compounds Nos. 47,699 and 47,644, respectively, have already been described3.
