Reductive Dimerization of CO by a Na/Mg(I) Diamide

[Image: see text] Sodium reduction of [{SiN(Dipp)}Mg] [{SiN(Dipp)} = {CH(2)SiMe(2)N(Dipp)}(2); Dipp = 2,6-i-Pr(2)C(6)H(3)] provides the Mg(I) species, [{SiN(Dipp)}MgNa](2), in which the long Mg–Mg bond (>3.2 Å) is augmented by persistent Na–aryl interactions. Computational assessment indicates th...

description [Image: see text] Sodium reduction of [{SiN(Dipp)}Mg] [{SiN(Dipp)} = {CH(2)SiMe(2)N(Dipp)}(2); Dipp = 2,6-i-Pr(2)C(6)H(3)] provides the Mg(I) species, [{SiN(Dipp)}MgNa](2), in which the long Mg–Mg bond (>3.2 Å) is augmented by persistent Na–aryl interactions. Computational assessment indicates that this molecule is best considered to comprise a contiguous tetrametallic core, a viewpoint borne out by its reaction with CO, which results in ethynediolate formation mediated by the dissimilar metal centers.
