G. Rousselet et al., COPPER(I)-INDUCED ADDITION OF AMINES TO UNACTIVATED NITRILES - THE 1ST GENERAL ONE-STEP SYNTHESIS OF ALKYL AMIDINES, Tetrahedron letters, 34(40), 1993, pp. 6395-6398
Cu(I)Cl promotes the condensation of acetonitrile la and benzonitrile
lb with primary and secondary amines 2a-g into amidines 3a-j under mil
d conditions, in high to quantitative yields. Stoichiometric formation
Of Cu(I)-amidines complexes allows to control the degree of substitut
ion of resulting amidines
