A straightforward and general method for the synthesis of annulated thiophene, dibenzothiophene, and carbazoles analogues has been achieved involving alkylation of 2-bromo-1-(phenylsulfonylmethyl)arene/heteroarene with arylmethyl bromides/heteroarylmethyl bromides using t-BuOK as a base in DMF, followed by Pd(0)-mediated intramolecular Heck coupling in the presence of K2CO3 in DMF at 80-140 °C. The attractive feature of this protocol is that a wide variety of π-conjugated heterocycles could be readily accessed by an appropriate choice of arylmethylsulfones and benzylic bromides.

An improved synthesis of phenanthrothiophene (6) from 1-chloro-3,4-dihydrophenanthrene-2-aldehyde (2) by condensation with thioglycolate followed by hydrolysis, decarboxylation and dehydrogenation is described.A new polycyclic thiophene derivative 14 has also been prepared from acenaphthothiophene (7) by Friedel-Craft's reaction with phthalic anhydride followed by lactonization of the keto carboxylic acid 9 and then reduction and finally cyclisation of the resultant aldehyde 13.
