The sequential substitution reactions of α,ω-diiodoalkanes with two units of 3-sulfolenyl anions conveniently lead to the formation of α,ω-alkanediylbis-(3-sulfolenes) 7. These bissulfolenes are stable precursors for the corresponding bis-(1,3-dienyl)alkanes 16 and the transformation can be readily achieved by a simple thermolytic cheletropic reaction.
