Catalytic amounts of 1,3-di(methyl)imidazole-2-ylidene, one of the simplest and most prototypical N-heterocyclic carbenes, can up-convert aldehydes into powerful stoichiometric sources of electrons (Super Electron Donors) for reductive transformations of iodoaryls (Ered < −2 V). In particular, the hydroarylation of 1,1′-diarylethylenes, which may require high temperatures and inherently generate stoichiometric
催化量的 1,3-二(甲基)咪唑-2-亚基(最简单和最具原型的 N-杂环卡宾之一)可以将醛上转换为强大的化学计量电子源(超级电子供体),用于碘芳基的还原转化( E红色< −2 V)。特别是,1,1'-二芳基乙烯的加氢芳基化可能需要高温并固有地产生化学计量量的氧化废物,但在室温下进行,同时形成作为氧化副产物的酯。
