Allylcopper intermediates with N-heterocyclic carbene ligands are synthesized by transmetalation of allylsiloxane reagents, and the crystal structures of allylcopper compounds are reported. The allylcopper transmetalation is utilized for catalytic aldehyde allylation, which is found to be facilitated by a trifluorosilane co-catalyst.
烯丙基铜中间体与 N-杂环卡宾配体通过烯丙基硅烷试剂的转金属化合成，并报道了烯丙基铜化合物的晶体结构。烯丙基铜的转金属化用于催化醛的烯丙基化，发现三氟硅烷助催化剂能促进该反应。
