Reactions of aliphatic ketones with lithium trimethylsilyl-diazomethane in the presence of excess olefins afforded methylenecyclopropanes in moderate to good yields. The multiplicity of the alkylidene carbene intermediate in the reacting state has been revealed to be a singlet.
在过量烯烃的存在下,脂肪族酮与三甲基甲硅烷基重氮甲烷锂的反应以中等至良好的产率提供了亚甲基环丙烷。已经发现处于反应状态的亚烷基卡宾中间体的多样性是单重态。
