A promoting effect of water was observed, leading to the dehydrative synthesis of allylic sulfones byTsuji–Trost reaction of non‐derivatized allylic alcohols with sulfinicacids. Mechanism studies suggested the formation of the eight‐membered ring complex from allylic alcohols, sulfinicacids, and water through hydrogen bonding may be crucial to the efficient activation of allylic alcohols.

The addition of Grignardreagents or organolithiumreagents to the SO2-surrogate DABSO generates a diverse set of metal sulfinates, suitable for direct conversion to sulfone products. The metal sulfinates can be trapped in situ with a wide range of C-electrophiles, including alkyl, allyl, and benzyl halides, epoxides, and (hetero)aryliodoniums.

A mild and green synthesis of allylic sulfones fromallylicalcohols and sulfonyl hydrazines was developed in water media. The simple and commercially available Pd(PPh3)4 is used as the best catalyst, and the reaction can proceed smoothly at 40 °C under air. This new method does not require the common nitrogen protection and organic media, and can be readily scaled up in gram scale, showing the good
