vinyl iodide with N-tosylhydrazone. This process involves palladium carbene migratory insertion/trapping with sulfinic acid salts. For the previous Pd-catalyzed N-tosylhydrazone cross-coupling, sulfinic acid salt is generated as a byproduct. In this transformation, the diazo compound and the sulfinic acid salt, which are all generated from N-tosylhydrazone, were used as cross-coupling partner.
通过碘化乙烯与N-甲苯磺酰P的钯催化交叉偶联,合成烯丙基砜具有优异的选择性和良好的收率。该过程涉及用亚磺酸盐迁移/捕获卡宾钯卡宾。对于先前的Pd催化的N-甲苯磺酰cross交叉偶联,会生成亚磺酸盐作为副产物。在该转化中,全部由N-甲苯磺酰generated产生的重氮化合物和亚磺酸盐用作交叉偶联伴侣。
