scope of the [2,3]‐sigmatropic rearrangement of propargylic sulfinates to allenic sulfones by silver catalysis was expanded. A series of new propargylic sulfinate esters was generated from a variety of aromatic and heteroaromatic sulfonyl chlorides and their rearrangement to allenic sulfones is reported. In addition, the synthesis of propargylic sulfinate esters containing electron‐withdrawing benzenesulfonyl
通过银催化,炔丙基亚磺酸盐[2,3]-σ重排为烯丙基砜的范围扩大了。从各种芳族和杂芳族磺酰氯生成了一系列新的炔丙基亚磺酸酯,并报道了它们被重排为烯丙基砜。此外,据报道含有吸电子的苯磺酰氯的炔丙基亚磺酸酯的合成。
