Abstract

Abstract A versatile synthetic route involving the use of organotin compounds has been applied for the preparation of functionalized oligothiophenes. Thus, substituted α- bithiophenes have been synthesized via the coupling reaction of 2-bromothiophenes with 2- trimethylstannylthiophene. The latter reagent couples with 2, 5-dibromothiophenes to give the α-terthiophenes which are also accessible through the reaction of 5-trimethylstannyl-α- ...
