摘要: By using an optically active metal-carbene complex we were able to isolate cyclopropane from the reaction of diethyl fumarate with [(−) (R)-methylphenylpropylphosphine] (phenylmethoxycarbene) tetracarbonylchromium. In addition being synthetically useful for preparation cyclopropanes optical activity, this demonstrates that no free carbene is involved in mechanism reaction.
