Benzofurano-, N -tosylindolo-, and benzothieno-3-sulfolenes have been prepared efficiently via their dihydro analogues. These fused 3-sulfolenes serve as ideal precursors for the corresponding heteroaromatic o -quinodimethanes. Derivatives of these 3-sulfolenes bearing bromo or alkyl group substitution from which substituted heteroaromatic o -quinodimethanes are generated have also been synthesized.
