reagents, under Wenkert Nickel-catalysed conditions, gave access to several substituted (Z)-alkenyl derivatives. These Nickel-catalysed reactions, carried out with vinyl-, phenyl-, p-methoxyphenyl-, trimethylsilylmethylmagnesium bromide and benzylmagnesium chloride, led to the corresponding (Z)-alkenyl derivatives in good yields and high stereoselectivities.
在Wenkert镍催化的条件下,用格氏试剂处理的(Z)-乙烯基(N,N-二异丙基)氨基甲酸酯可得到几种取代的(Z)-烯基衍生物。用乙烯基-,苯基-,对-甲氧基苯基-,三甲基甲硅烷基甲基溴化镁和苄基氯化镁进行的这些镍催化的反应以高收率和高立体选择性产生相应的(Z)-烯基衍生物。
