We herein first report the homodimerization and tandem diamination of diazo compounds with primary amines catalyzed by iron(II) phthalocyanine (PcFe(II)), which can construct one C-C bond two C-N bonds within 20 min in one-pot. Compared to traditional metal-catalyzed N-H insertion reaction between reagents, developed almost does not generate product, but homodimerization/tandem product. The proposed mechanism studies indicate that play a crucial role homocoupling via dimerization iron(III)-acetonitrile radical generated from diazoacetonitrile PcFe(II) coordinated bis(amines); β-hydride elimination is involved, then, attack toward carbon atoms on formed followed. Moreover, this novel be used effectively prepare substituted 2,3-diaminosuccinonitriles high yields even up >99:1 d.r., encouragingly these products contain both 1,2-diamines succinonitrile motifs, are classes important organic significant applications many yields. This also suitable for gram-scale preparation 2,3-bis(phenylamino)succinonitrile (
