bimetallic species resulted in the generation of a highly nucleophilic and practically convenient chloromethylenetitanium complex, which efficiently effected condensation even with enolizable or inert carbonyl compounds, such as sterically congested ketones, to provide vinyl chloride compounds.
将CHCl 3直接氧化添加到Mg-TiCl 4双金属物质中,导致生成高度亲核且实用的氯亚甲基钛配合物,即使与可烯化或惰性的羰基化合物(例如空间拥挤的酮)也能有效地进行缩合,从而提供氯乙烯化合物。
