研究了一种钯催化的磺化偶联反应，用于磺酰肼和碳酸盐合成苄基（烯丙基）砜。新方法采用易于获得的化学原料，包括稳定和容易获得的芳基磺酰肼和苯（烯丙基）碳酸酯。在温和的条件下，在Pd(dppf)Cl2的存在下，在不添加碱的情况下，可以得到多种苯（烯丙基）砜。
An efficient palladium-catalyzed sulfonylative coupling for the synthesis of benzyl(allyl) sulfones from sulfonyl hydrazides and carbonates was developed. The novel methodology employs easily accessible chemical feedstocks including stable and readily available arylsulfonyl hydrazides and benzyl(allyl) carbonates. A variety of benzyl(allyl) sulfones could be obtained in good to excellent yields in the presence of Pd(dppf)Cl2 without additional base under mild conditions.
