Cyclopropylmethyl palladium species can be accessed by Pd-catalyzed reaction of either cyclopropyl N-tosylhydrazone with halide or N-tosylhydrazone with cyclopropyl halide. In both approaches migratory insertion of Pd carbene is the key process. These transformations constitute new approaches toward 1,3-butadiene derivatives.
环丙基甲基钯物质可通过环丙基N-甲苯磺酰to与卤化物或N-甲苯磺酰with与环丙基卤化物的Pd催化反应获得。在这两种方法中,Pd卡宾的迁移插入都是关键过程。这些转变构成了针对1,3-丁二烯衍生物的新方法。
