the functionalization of unactivated olefins with carbon nucleophiles have provided more efficient and practical approaches to convert inexpensive starting materials into valuable products. Recent examples have been reported with stabilized carbon nucleophiles, tethered carbon nucleophiles, diazoesters, and trifluoromethane donors. A general method for functionalizing olefins with aromatic, aliphatic
用碳亲核试剂对未活化烯烃进行功能化方面的新进展为将廉价的原材料转化为有价值的产品提供了更有效和实用的方法。最近报道了稳定碳亲核试剂、系链碳亲核试剂、重氮酯和三氟甲烷供体的例子。开发了一种用芳香族、脂肪族和乙烯基格氏试剂官能化烯烃的通用方法。在单锅法中,烯烃通过市售试剂被氧化成烯丙基亲电试剂,后者与格氏试剂进行选择性铜催化烯丙基烷基化。产物以高产率和高区域选择性形成。这被用来合成一系列跳过的二烯,
