Acid chlorides react with SmI2 to give α-diketones. Various experiments show that the initially formed acyl radical is rapidly transformed into an acyl anion which is thus generated by quite an unusual route.

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.
