The intermolecular reductive coupling of 1,1-diaryl-2,2-dicyanoethylenes or 1,1-diaryl-2-cyano-2-ethoxycarbonylethylenes with aromatic nitriles induced by samarium(II) iodide has been studied. Polysubstituted 3H-pyrroles were prepared in good to excellent yields under neutral and mild conditions.

The intermolecular reductive coupling of 1,1-diaryl-2,2-dicyanoethylenes or 1,1-diaryl-2-cyano-2-ethoxycarbonylethylenes with aromatic nitriles induced by samarium and catalytic iodine was studied. 3H-Pyrroles were prepared in moderate to good yields under neutral and mild conditions.
