On the Side-Chain Bromination of 3-Methylselenophene and 3-Methylthiophene

Abstract

3-Bromomethylselenophene can be prepared from 3-methyl-selenophene, N-bromosuccinimide and azo-bis-isobutyronitrile in carbon tetrachloride in 25% yield with the reversed addition method described in this paper. The method also gives consistently high yields of 3-bromomethylthiophene (70–75%) when applied on 3-methylthiophene.
