sulfinate salt, allylic sulfones were synthesized by palladium‐catalyzed cross‐coupling of aryl iodide with N‐tosylhydrazone. In this transformation, not only the diazo compound but also the sulfinate salt, which were both generated in situ from base‐mediated decomposition of the N‐tosylhydrazone, was used as nucleophilic partner.
在不额外添加亚磺酸盐的情况下,通过钯催化的芳基碘化物与N-甲苯磺酰基cross的交叉偶联合成了烯丙基砜。在该转化过程中,不仅重氮化合物而且亚磺酸盐(它们都是由N-甲苯磺酰base的碱介导分解原位生成的)都被用作亲核伴侣。
