Gallium trichloride (GaCl3) catalyzes the ethynylation reaction of a 1,4-enyne with chlorosilylacetylene at the propargyl position giving a triethynylvinylmethane. This catalytic method can be applied to the exhaustive α-ethynylation of 1-silylacetylenes possessing less acidic propargyl protons, and mono-, di-, and triethynylated products are obtained depending on the structure of the starting materials
三氯化镓(GaCl 3)催化1,4-炔与炔丙基位置的氯甲硅烷基乙炔进行乙炔化反应,得到三乙炔基乙烯基甲烷。该催化方法可以用于具有较少酸性炔丙基质子的1-甲硅烷基乙炔的穷举α-乙炔基化,并且取决于起始原料的结构获得单,二和三乙炔基化的产物。
