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.

Acid halides are known to be reductively coupled with aldehydes and ketones in the presence of samariumdiiodide to generate α-hydroxy ketones. Low yields coupled product are obtained due to the competitive process of tetrahydrofuran attack on the acid chloride. This competitive reaction can be avoided and yields improved by preparation of samariumdiiodide in acetonitrile.
