A [1,2] M(CO)5 shift promotes a [3,4] sigmatropic rearrangement after the addition of allylic alcohols to Fischer alkenylcarbene complexes of tungsten or chromium in the presence of alkoxide ions. This opens a new synthetic route to the adducts 1. The reaction is also applicable to propargylic alcohols. [M]=Mo(CO)5 , W(CO)5 .
在醇盐离子存在下向钨或铬的费希尔烯基碳烯络合物中添加烯丙基醇后,[1,2] M(CO)5移位促进了[3,4]σ重排。这为加合物1开辟了一条新的合成路线。该反应也适用于炔丙醇。[M] = Mo(CO)5,W(CO)5。
