(Alkoxymethyl)-, (aminomethyl)-, (2-alkoxyethenyl)-, (2-acetoxyethenyl)-, and (2-siloxyethenyl)cyclopropanes are obtained in high yields by reaction of allyl alcohol or derivatives, allylamines, 1-alkoxy-, 1-acetoxy-, and 1-trimethylsiloxy-1,3-butadienes with diazomethane in dichloromethane/diethyl ether in the presence of bis(benzonitrile)palladium dichloride.
通过在二氯甲烷/二乙醚中在二氯化双(苯腈)钯的存在下,使烯丙醇或其衍生物、烯丙胺、1-烷氧基、1-醋酸基和1-三甲基硅氧基-1,3-丁二烯与二氮甲烷反应,可以高产率地获得(烷氧基甲基)-、(氨基甲基)-、(2-烷氧基乙烯基)-、(2-醋酸氧基乙烯基)-和(2-硅氧基乙烯基)环丙烷。
