  Synthesis of new mixed-alkyl rhenium(VII) organoimido complexes and a new facile route to Me3SiORe(NBut)3

  摘要：

  Alkylation of the rhenium(VII) dichloro compound of the formula MeRe(NR')2 Cl2PY (1) with MeMgCl, Et2Zn and Pr(i)MgCl yields the d0 trialkyl diimido complexes of the formula MeR2Re(NR')2 (2a-c) (R=Me, Et, Pr(i); R'=2,6-dimethylphenyl). Compound 2a is stable at 25-degrees-C, while compounds 2b and c decompose within a few hours. In a similar manner the alkylation of the new tert-butyl imido derivative MeRe (NBu(t))2Cl2 (4) [prepared from MeRe(NBu(t))3 (3) by hydrochlorination] yields the tri-alkyl complexes of the formula MeR2Re(NBu(t))2 (5a-c) (R = Me, Et and Pr(i)), of which the mixed-alkyl species are again thermolabile. Analysis of the gas-phase decomposition products revealed a rather complex decomposition pathway, in which the beta-hydrogen elimination is likely to play a minor role. Reaction of the polymeric oxo species of the formula Me3SnOReO3 (6) with the silylamine Bu(t)NHSiMe3 gives, surprisingly cleanly, the monomeric tris-imido compound of the formula Me3SiORe(NBu(t))3 (7) in 93% yield.

  Reaction of ReMeO3 and 2,6-dimethylphenyl isocyanate gives the imido complex [ReMe(NR)3] (R = 2,6-Me2C6H3). Complexes of the type [ReMe(NR)3] or [ReMe(NBu(t))3] undergo selective substitution of only one imido ligand to form bis(imido) derivatives. Thus, [ReMe(NBu(t))3] reacts with the weak acid catechol via protonation of one imido ligand to form a stable five-co-ordinate complex [ReMe(NBu(t))2(O2C6H4)]. In contrast, [ReMe(NR)3] forms a complex which can only be isolated in a pure state by the addition of pyridine (py) to give the six-co-ordinate [ReMe(NR)2(O2C6H4)(py)]. The complex [ReMe(NR)3] also reacts with thiophenol to give five-co-ordinate [ReMe(NR)2(SPh)2]. Reaction of [ReMe(NR)3] with HCl gives the ionic complex [NH3R][ReMeCl3(NR)2]. The crystal structure of this complex was determined by X-ray crystallography. The neutral dihalide complexes [ReMe(NR)2X2(py)] (X = Cl or Br) are prepared from [ReMe(NR)3] by the addition of 2 equivalents of pyridinium halide. Alkylation of the dichloro or dibromo derivative with neopentylmagnesium chloride gives the novel mixed-alkyl complex [ReMe(CH2Bu(t))2NR)2] as a mixture of two isomers, the structure of one of which was determined by X-ray crystallography.
