Abstract

The electrophilic trichloromethylation of 3-chloro-, 3-bromo-, and 3,4-dibromothiophene was studied. It is shown that reaction is directed towards position 2, accompanied by frequent formation of the corresponding substituted di-(2-thienyl)dichloromethane. Trichloromethylation of β-bromothiophenes is complicated by exchange of chlorine for bromine under the reaction conditions.
