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 delta or epsilon positions to give highly complex polycycles, which are otherwise hard to access.
由1-(2-炔基苯基)六-5-烯-1-酮和Pt(II)生成的异丙烯腈-4-基铂(II)与侧链烯烃通过[3 + 2]环加成反应形成四环Pt -卡宾配合物,在CH的δ或ε位置进行苄基插入,生成高度复杂的多环,否则很难获得。
