Oxidative S-dealkylation of tert-butyl aryl sulphides: a novel route to 3-substituted-3H-1,2-benzodithioles
Abstract
Substituted 3H-1,2-benzodithioles are readily synthesized by an oxidative S-dealkylation reaction of mercapto tert-butyl sulphides 8 with N-bromosuccinimide in acetonitrile without prior deprotection of the tert-butyl group.
