• W2068935595 abstract "The synthesis and reactivity of a wide range of titanium benzamidinates is described. Addition of 0.5 equiv of Me2Mg to the dichloride L2TiCl2 (L = PhC(NSiMe3)2) in Et2O yields the chloro−alkyl derivative L2Ti(Me)Cl in good yield. The addition of 2 equiv of PhCH2MgCl to the dichloride affords thermally sensitive L2Ti(CH2Ph)2 in moderate yield. Likewise, addition of 1 equiv of Me2Mg results in the clean formation of the dimethyl L2TiMe2. The dimethyl reacts with tert-butylamine in refluxing benzene to form the five-coordinate imido L2TiNCMe3, for which crystallographic data is presented. The imido reacts with acetone in C6D6 to form the bridging oxo derivative L2Ti(μ-O)2TiL[η1-NC(Ph)N(SiMe3)2]. Overnight reduction of the dichloride with 1% Na/Hg amalgam in tetrahydrofuran (THF) forms the Ti(III) derivative L2TiCl(THF), which is crystallized from hexanes in moderate yield. Carrying out the analogous reduction in toluene yields the base-free Ti(III) chloride, L2TiCl, for which crystallographic data is presented. Allowing the reaction (in toluene) to proceed for an additional 48 h results in further reduction and the formation of the end-on bound dinitrogen complex (L2Ti)2(μ-N2), which is isolated as dark blue crystals from hexanes in moderate yield. Reduction of L2Ti(Me)Cl with 1% Na/Hg amalgam in THF forms the Ti(III) methyl derivative which is isolated as the five-coordinate THF-free product L2TiMe upon evacuation and crystallization from hexamethyldisiloxane (HMDSO). The related Ti(III) alkyl L2TiCH2SiMe3 is readily prepared by reaction of LiCH2SiMe3 with L2TiCl in toluene. Carrying out the 1% Na/Hg amalgam reduction of the dichloride in the presence of CO results in the formation of the Ti(III) bridging-oxo species (L2Ti)2(μ-O), which is isolated in low yield. CO as the sole oxygen source is confirmed by the use of C18O, which yielded only labeled product. Analogous reduction in the presence of N,N,N‘,N‘-tetramethylethylenediamine (TMEDA) results in the C−N bond cleavage of an amidinate ligand and the cyclometalation of TMEDA. Two products, L2TiNSiMe3 and LTi[η2-Me3SiNC(H)Ph][η3-CH2N(Me)CH2CH2NMe2], are isolated in good yields by fractional crystallization from hexanes. The dinitrogen complex, (L2Ti)2(μ-N2), reacts with pyridine (Py) and 2,6-dimethylphenyl isocyanide (XylylNC) to form base adducts [L2Ti(Py)]2(μ-N2) and [L2Ti(CNXylyl)]2(μ-N2) without loss of the dinitrogen ligand. Crystallographic data for the Py adduct is presented. Oxidation reactions of (L2Ti)2(μ-N2) with a variety of oxygen and sulfur sources is reported. Reaction with dry O2 in the presence of pyridine gives the seven-coordinate peroxo complex L2Ti(η2-O2)Py. The related reaction with excess S8 yields the dark-green persulfido derivative L2Ti(η2-S2), for which crystallographic data is presented. The persulfido reacts overnight with Hg in toluene solution to give the bimetallic sulfido complex L2Ti(μ-S)2TiL[η1-NC(Ph)N(SiMe3)2], which is formed following a silyl-group migration. The analogous oxygen-containing product is best prepared by the reaction of powdered (L2Ti)(μ-N2) with dry O2. In the presence of excess pyridine, L2Ti(η2-S2) reacts with Hg to yield the terminal sulfido L2Ti(S)Py. The crystallographically characterized terminal-oxo derivative L2Ti(O)OPy is prepared by reaction of (L2Ti)(μ-N2) with an excess of pyridine N-oxide in toluene−pyridine." @default.
