Lh. Zhou et Ym. Zhang, Facile synthesis of amidines via the intermolecular reductive coupling of nitriles with nitro compounds induced by samarium(II) iodide, J CHEM R-S, (9), 1998, pp. 596-597
The intermolecular reductive coupling of nitriles with nitrocompounds induc
ed by SmI2 was studied; amidine derivatives are prepared in good yields und
er neutral and mild conditions.
