The reduction of a diphenyl alpha -iminoketone with samarium diiodide has b
een studied. A fast two-electron transfer gives a samarium (Z)-enamidolate,
which is protonated to afford an alpha -aminoketone or reacted with a vari
ety of ketones to furnish pyrrole derivatives. Possible mechanisms are prop
