Titanium(III) π-allyliccomplexes, 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.

ketones have been examined, and three main trends emerge as criteria to distinguish the two conformations. By use of these criteria some labile αβ-unsaturated ketones have been assigned conformations which are believed to predominate at room temperature, although for a number of the ketones the actual conformation is probably non-planar.
