Abstract

Self-assembled pseudocyclic structures consisting of two molecules of a crown-containing butadienyl dye and two Mg(2+) ions readily undergo regio- and stereospecific [2+2] photocycloaddition in MeCN to produce a single cyclobutane stereoisomer in almost quantitative yield.

摘要

由两个含有冠醚的丁二烯染料分子和两个 Mg(2+) 离子组成的自组装拟环结构，在 MeCN 中很容易进行区域和立体特异性的[2+2]光环加成反应，几乎以定量产率生成单一的环丁烷立体异构体。
