T. Muller et al., A NEW PROCESS FOR PREPARING DIBROMIDES BY DECARBOXYLATION OF UNSATURATED-ACIDS WITH NBS, Synthetic communications, 28(13), 1998, pp. 2343-2354
The Wolf-Ziegler reaction carried out in CCl4 or chlorobenzene on unsa
turated acids was found to give the isomeric mono, di or tri bromide p
roducts corresponding to a decarboxylation process, instead of the exp
ected allylic substitution reaction. Some of the compounds thus prepar
ed can constitute key intermediates in further synthesis and they are
required in great quantities.
