Abstract

Abstract: Photolysis of vinyl halides in the presence of copper (I1) salts resulted in a significant suppression of product formation derived from vinyl radicals. Photolysis of l, l- diaryl-2-bromopropenes in the presence of copper (I1) salts yielded no 1, l-diaryl-2- propenes. Photolysis of other vinyl halides, Le., 1, l-diaryl-2-iodopropenes, 1, 1-diaryl-2- bromoethylenes, and 1-bromo-2-(p-methoxyphenyl) ethylene, also led to a large decrease ...
