Very couply! Coupling reactions of propargyl or benzyl alcohols with allyl‐ or alkynylsilanes proceed efficiently using [{ReBr(CO) 3 (thf)} 2 ] as catalyst. Additionally, diethynylmethane derivatives were obtained by the reaction of aromatic aldehydes with trimethyl(phenylethynyl)silane in the presence of both the rhenium complex and AuCl (see scheme).
