[{SiNDipp}MgNa](2) reacts directly with H-2 to form a heterobimetallic hydride. Computational density functional theory (DFT) studies suggest that this reactivity is initiated by orbitally-constrained sigma(Mg-Mg)-> sigma*(H-H) and sigma(H-H) -> n*(Na(3s)) interactions between the frontier MOs of both H-2 and the tetrametallic core of [{SiNDipp}MgNa](2).
[{SiNDipp}MgNa](2) ({SiNDipp} = {CH2SiMe2N(Dipp)}(2); Dipp = 2,6-i-Pr2C6H3) reacts directly with H-2 to provide a heterobimetallic hydride. Although the transformation is complicated by the simultaneous disproportionation of magnesium, computational density functional theory (DFT) studies suggest that this reactivity is initiated by orbitally-constrained sigma(Mg-Mg)-> sigma*(H-H) and sigma(H-H) -> n*(Na(3s)) interactions between the frontier MOs of both H-2 and the tetrametallic core of [{SiNDipp}MgNa](2).
