Phosphaguanidines as scaffolds for multimetallic complexes containing metal-functionalized phosphines.

Phospha(III)guanidines, R2PC{NR'}{NHR'}, have been used to synthesize multimetallic compounds containing combinations of aluminum with platinum or copper, in which the main-group metal is N,N'-bound by an amidinate moiety, thereby generating a metal-functionalized phosphine that bonds to the transition metal through phosphorus.
