Air promoted intermolecular annulation of thiophenols with alkynes, leading to complex benzothiophenes, is reported. This atom-economical reaction is performed in the absence of any catalyst, chemical oxidant and additive. Only a solvent and an air atmosp

A series of new type of benzo[b]thiophene-fused 1,4-benzoquinones and their tetracyanoquinodimethane derivatives were synthesized. The cyclic voltammetric data of new type quinones and tetracyanoquinodimethane derivatives displayed different behavior. All new quinones exhibit two reduction waves corresponding to the radical anion and dianion. On the other hand, most tetracyanoquinodunethane derivatives display a singlewave reduction to the dianion. The benzo[b]thiophene moiety fused tetracyanoquinodimethane derivatives reveal more negative reduction potentials than that of tetracyanoquinodimethane.
