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.
