Abstract
Isochromenylium-4-ylplatinum(II) species, generated from 1-(2-alkynylphenyl)hex-5-en-1-ones and Pt(II), reacted with a pendant olefin via [3+2] cycloaddition to form tetracyclic Pt-carbene complexes, which underwent C-H insertion with a benzyloxy group at δ or ε positions to give highly complex polycycles, which are otherwise hard to access.
摘要
异环戊二烯基铂(II)物种，由 1-(2-炔基苯基)己-5-烯-1-酮和 Pt(II)生成，与侧链烯烃通过[3+2]环加成反应形成四环 Pt-卡宾配合物，该配合物与 δ 或 ε 位的苄氧基进行 C-H 插入反应，得到高度复杂的多环化合物，否则很难获得。
