By the use of samarium diiodide (SmI2), a cross-coupling reaction of aldehydes with α-diketones smoothly proceeds in the presence of water to give the corresponding adducts in moderate to good yield. In this reaction, it is possible to use the substrates such as phenylglyoxal monohydrate, aqueous methylglyoxal, formalin, and aqueous α-chloroacetaldehyde.

In the presence of bismuthtrichloride and metallic zinc, α-diketones react with aldehydes in THF under reflux to afford the corresponding α,β-dihydroxyketones in moderate to good yields. It was also found that the present reaction proceeds smoothly by using a catalytic amount of bismuthtrichloride to give the corresponding adducts. The present reaction takes place even in aqueous media.
