Nitrene-Transfer Chemistry to C-H and C═C Bonds Mediated by Triangular Coinage Metal Platforms Supported by Triply Bridging Pnictogen Elements Sb(III) and Bi(III).

ABSTRACT: Tripodal ligands (TMG₃trphen-E) that feature heavy pnictogen elements (E = Sb(III), Bi(III)) and tetramethylguanidinyl (TMG) arms have been explored in stabilizing Cu(I) and Ag(I) sites and facilitating nitrene-transfer chemistry. Compounds [(TMG₃trphen-E)M₃(μ-X)₃] (M = Cu(I), Ag(I); X = Cl, Br, I) have been generated upon extraction of M₃(μ-X)₃ units from MX sources, exhibiting support of the crown-shaped M₃(μ-X)₃ fragment by M-N_TMG bonds and triply bridging E → M₃ interactions. Orbital interactions between Cu(I) sites and N_TMG residues are more dominant than Sb/Bi → Cu₃ donor interactions between the Sb 5s or Bi 6s orbitals and admixed C
