Addition of alkenyl Grignard reagents to (1-methoxycarbonylpentadienyl)iron(1+) cation generates the corresponding (2-alkenylpent-3-en-1,5-diyl)iron complexes. Oxidatively induced-reductive elimination of these complexes gives divinylcyclopropanes which can undergo subsequent Cope rearrangement to give 1,4-cycloheptadienes.
将烯基格氏试剂添加到 (1-methoxycarbonylpentadienyl)iron(1+) 阳离子生成相应的 (2-alkenylpent-3-en-1,5-diyl) 铁配合物。这些配合物的氧化诱导还原消除产生二乙烯基环丙烷,其可以进行随后的 Cope 重排以产生 1,4-环庚二烯。
