Abstract: A new method to prepare phenanthro[9,10-c]thiophenes has been developed. In the presence of triflic acid, 3,4-diaryl thiophenes undergo 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ)-promoted cyclo-oxidation. NMR and computational studies indicate that protonation of the thiophene plays a key role… read more here.

Abstract: Abstract Three new charge transfer (CT) complexes consisting of brucine (Bru) as the electron donor and chloranilic acid (ChA), 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) or 7,7,8,8-tetracyanoquinodimethane (TCNQ) as the electron acceptors were synthesized. These complexes were characterized using… read more here.
