    C–H Bond Activations by Monoanionic, PNP-Supported Scandium Dialkyl Complexes
    摘要:
    A series of scandium dialkyl complexes, (PNP)ScR2 (R = neopentyl, trimethylsilylmethyl), supported by the monoanionic, chelating PNP ligand (2,5-bis(dialkylphosphinomethyl)-pyrrolide; alkyl = cydohexyl, tert-butyl) was synthesized, and the reactivities of these complexes toward simple hydrocarbons was investigated. The scandium-carbon bonds undergo sigma-bond metathesis reactions with hydrogen, and these complexes are catalysts for the hydrogenation of alkenes. Reactions with primary amines led to formation of amido complexes that undergo cyclometalation via sigma-bond metathesis, without involvement of an imido complex intermediate. A variety of carbon-hydrogen bonds are also activated, including sp-, sp(2)-, and sp(3)-C-H bonds (intramolecularly in the latter case).

    titanium-containing product of this reaction is a titanium alkylidene, which in solution activates C-H bonds of both saturated and unsaturated hydrocarbon solvents such as benzene and cyclohexane. No activation of the C-F bonds of hexafluorobenzene is seen, however. Under special circumstances, a second thermolysis pathway for TiNp4 can be detected, A-hydrogen activation, but this pathway is intrinsically about 25
