The environmentally friendly and inexpensive organoaluminum compound, diisobutylaluminum hydride (HAliBu2), acts as an efficient pre-catalyst for C-C bond formation by the addition of terminal alkynes to carbodiimides, which is a rare sample that the group 13 complexes to be used for catalyzing such reactions. Preliminary mechanistic studies revealed that the reaction is mainly carried out by initial
环保且廉价的有机铝化合物二异丁基氢化铝 (HAl i Bu 2 ) 通过将末端炔烃加成到碳二亚胺中,作为 CC 键形成的有效预催化剂,这是第 13 族络合物使用的罕见样品用于催化此类反应。初步的机理研究表明,该反应主要是通过首先对碳二亚胺进行加氢铝化,然后再用乙炔进行质子分解来进行的。碳化二亚胺分子被插入到生成的炔基铝化合物的 Al-C 键中。通过与乙炔的第二次质子分解获得最终产物。
