乙炔二甲酸二甲酯与2摩尔当量的B(C6 F5)3通过C6 F5转移到中心炔属C = C键,形成尾对尾偶联的双(硼酯烯醇化物)体系。该独特体系的中心六取代丁二烯单元与马来酸二甲酯在Diels-Alder反应中反应,得到氢醌衍生物。
Dimethyl acetylenedicarboxylate reacts with 2 mol‐equiv. B(C6F5)3by C6F5transfer to the central acetylenic C≡C bond with formation of a tail‐to‐tail coupled bis(boron ester enolate) system. The central hexasubstituted butadiene unit of this unique system reacts with dimethyl maleate in a Diels–Alder reaction to give a hydroquinone derivative.
