[reaction: see text] A conjugated pi-electron compound, 2-aryl-3-silyl-1,3-butadiene, was easily prepared from 1-benzyloxy-3-silyl-2-propyne, bis(iodozincio)methane, and an aryl halide in the presence of nickel catalyst. A subsequent cross-coupling reaction of the product with another aryl halide gave an unsymmetrical 2,3-diaryl-1,3-butadiene efficiently.
[反应:见正文]可以轻松地从1-苄氧基-3-甲硅烷基-2-丙炔,双(碘并甲烷)甲烷和二碘甲烷制备共轭π电子化合物2-芳基-3-甲硅烷基-1,3-丁二烯。在镍催化剂存在下的芳基卤化物。随后产物与另一种芳基卤的交叉偶联反应有效地产生了不对称的2,3-二芳基-1,3-丁二烯。
