Treatment of alkenes with "thicyanogen bromide" prepared from equimolar amounts of bromine and thallium (1) thiocyanate in wet chloroform, gives moderate to high yields of vic-bromothiocyanates.The addition proceeds by an ionic mechanism involving nucleophilic attack of bromide ion on anS-cyanothiiranium cation.Unlike vic-iodothiocyanates, the vic-bromothiocyanates are not readily isomerized to the corresponding vic-halogenoisothiocyanates.
