摘要

The Wolf-Ziegler reaction carried out in CCl4 or chlorobenzene on unsaturated acids was found to give the isomeric mono, di or tri bromide products corresponding to a decarboxylation process, instead of the expected allylic substitution reaction. Some of the compounds thus prepared can constitute key intermediates in further synthesis and they are required in great quantities. [References: 7]
