  Nitrene Metathesis and Catalytic Nitrene Transfer Promoted by Niobium Bis(imido) Complexes

  摘要：

  We report a metathesis reaction in which a nitrene fragment from an isocyanide ligand is exchanged with a nitrene fragment of an imido ligand in a series of niobium bis(imido) complexes. One of these bis(imido) complexes also promotes nitrene transfer to catalytically generate asymmetric dialkylcarbodiimides from azides and isocyanides in a process involving the Nb(V)/Nb(III) redox couple.

Additionally, the Lewis base-free dichlorides of the tBu-imido and Ar-imido (Ar = 2,6-iPr2-C6H3) complexes were obtained following treatment of Nb(NR)Cl3(dme) (R = tBu, Ar) with Li(BDI)(OEt2). The pyridine-coordinated dichloride was alkylated and arylated to form the dimethyl complex (BDI)Nb(NtBu)Me2 (described

  The bis(imido) complexes (BDI)Nb(NtBu)2 and (BDI)Nb(NtBu)(NAr) (BDI = N,N′-bis(2,6-diisopropylphenyl)-3,5-dimethyl-β-diketiminate; Ar = 2,6-diisopropylphenyl) were shown to engage in 1,2-addition and [2 + 2] cycloaddition reactions with a wide variety of substrates. Reaction of the bis(imido) complexes with dihydrogen, silanes, and boranes yielded hydrido-amido-imido complexes via 1,2-addition across

  Reported. herein is the unusual reactivity of (BDI)Nb((NBu)-Bu-t)(2) (BDI = N,N'-diaryl-beta-diketiminate, aryl = 2,6-Pr-i(2)-C6H3) with AlBr3. These investigations led to the synthesis and isolation of heterometallic complex (BDI)Al(mu-(NBu)-Bu-t)(mu-Br)Nb((NBu)-Bu-t)Br-2, which was both structurally and spectroscopically characterized.
