Coupling reactions of acid chlorides are mediated by SmI2 and SmCp2, leading to alpha-ketols 3. Condensation reactions of acid chlorides on aldehydes similarly product alpha-ketols 5; with ketones, best results are obtained with use of SmI2. Reactivities of SmI2 and SmCp2 are compared and mechanisms of the reactions discussed. Formation of an acylsamarium species is shown.
