Abstract

Abstract : A series of new unsymmetrical benzotrichalcogenophenes (BTCs) were synthesized by the Pd–N-heterocyclic carbene catalyzed intramolecular C3-arylation of furan, thiophene, selenophene and tellurophene units. Abstract : A series of new unsymmetrical benzotrichalcogenophenes (BTCs) were synthesized by the Pd–N-heterocyclic carbene catalyzed intramolecular C3-arylation of furan, thiophene, selenophene and tellurophene units. This is the first time that a C3-direct arylation of selenophene and tellurophene moieties has ever been demonstrated.
