An efficient and practical method for a scalable synthesis of 3-arylbutadiene sulfones deals with the ligand-free Heck–Matsuda reaction of sulfolene with aryldiazonium tetrafluoroborates followed by triethylamine-promoted double bond shift.

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.

Efficient routes have been developed for the synthesis of benzothieno-3-sulfolene 15, benzofurano-3 sulfolene 16, and N-tosylindolo-3-sulfolene 18. These compounds are ideal precursors for the corresponding heteroaromatic o-quinodimethanes.
