  Tris(oxazolinyl)boratomagnesium-Catalyzed Cross-Dehydrocoupling of Organosilanes with Amines, Hydrazine, and Ammonia

  摘要：

  We report magnesium-catalyzed cross-dehydrocoupling of Si-H and N-H bonds to give Si-N bonds and H-2. A number of silazanes are accessible using this method, as well as silylamines from NH3 and silylhydrazines from N2H4. Kinetic studies of the overall catalytic cycle and a stoichiometric Si-N bond-forming reaction suggest nucleophilic attack by a magnesium amide as the turnover-limiting step.

  The rare-earth bis(alkyl) compound SmC(SiHMe2)(3)}(2)THF2 (1b) is prepared by the reaction of samarium(II) iodide and 2 equiv of KC(SiHMe2)(3). This synthesis is similar to that of previously reported YbC(SiHMe2)(3)}2THF(2) (la), and compounds la,b are isostructural. Reactions of lb and 1 or 2 equiv of B(C6F5)(3) afford SmC(SiHMe2)(3)HB(C6F5)(3)THF2 (2b) or SmHB(C6F5)(3)}2THF(2) (3b), respectively, and 1,3-disilacyclobutane Me2Si-C(SiHMe2)(2)}(2) as a byproduct. Bands from 2300 to 2400 cm(-1) assigned to vBH in the IR spectra and highly paramagnetically shifted signals in the 1113 NMR spectra of 2b and 3b provided evidence for Sm-coordinated HB(C6F5)(3). Compounds la,b react with the bulky N-heterocyclic carbene (NHC) 1,3-di-tert-butylimidazol-2-ylidene (ImtBu) to displace both THF ligands and give three-coordinate monoadducts LnC(SiHMe2)(3)}(2)]mtBu (Ln = Yb (4a), Sm (4b)). Complexes 4a,b catalyze cross-dehydrocoupling of organosilanes with primary and secondary amines at room temperature to give silazanes and 112, whereas la,b are not effective catalysts under these conditions. Second-order plots of In[Et2NH]/[Ph2SiH2]} vs time for 4a-catalyzed dehydrocoupling are linear and indicate first-order dependences on silane and amine concentrations. However, changes in the experimental rate law with increased silane concentration or decreased amine concentration reveal inhibition by silane. In addition, excess ImtBu or THF inhibit the reaction rate. These data, along with the structures of 4a,b, suggest that the bulky carbene favors low coordination numbers, which is important for accessing the catalytically active species.
