A highly polar hypervalent SIV[BOND]SII bond was formed in the synthesis of a sulfur-substituted sulfurane (see scheme), which was crystallographically characterized. Reduction of the 1,2-dithietane gives the corresponding thiol, and reoxidation gives the sulfurane by S[BOND]S bond reformation. Thermal decomposition leads to a cyclic sulfenate and a thiirane.
