Two very distinct chemical reactions, yet a single catalyst: A gold complex promotes the formation of tertiary enamines from a variety of terminal and internal alkynes. Subsequent addition of a terminal alkyne to the reaction mixture affords allenes (see scheme).
两种截然不同的化学反应,但只有一种催化剂:金络合物促进各种末端和内部炔烃形成叔烯胺。随后向反应混合物中添加末端炔得到丙二烯(参见方案)。
