Titanium(III) π-allylic complexes, prepared by the interaction of 1,3-dienes or trienes with Cp2TiCl2 and n-PrMgBr, react with carboxylic acid chlorides RCOCl (R = alkyl, aryl, alkenyl) to give β, γ-unsaturated ketones in high yields. The reaction takes place at the most substituted carbon atom of the π-allylic ligand.
由1,3-二烯或三烯与Cp 2 TiCl 2和n-PrMgBr相互作用制得的钛(III)π-烯丙基配合物与羧酸氯化物RCOCl(R =烷基,芳基,烯基)反应生成β, γ-不饱和酮,收率高。该反应在π-烯丙基配体的最取代的碳原子处发生。
