Syntheses and properties of molecular nickel(II) hydride, methyl, and nickel(I) complexes supported by trimethylphosphane and (2-diphenylphosphanyl)thiophenolato and -naphtholato ligands
摘要:
2-Diphenylphosphanyl) thiophenol (PpSH) or (3-diphenylphosphanyl)-2-thionaphthol (PnSH) react with Ni(PMe3)(4) to form NiH(PpS)(PMe3)(2) (1) or NiH(PnS)(PMe3)(2) (2). 1,3-Bis(diphenylphosphanyl) propane (PP) replaces the monodentate phosphane ligands to give NiH(PpS)(PP) (3). NiMe(OMe)(PMe3) or NiMe2(PMe3)(3) react with PpSH to form NiMe(PpS)(PM3) (4) and NiMe( PpS)( PMe3)(2) (5), respectively, and PnSH affords NiMe(PnS)(PMe3)(2) (6), NiMe(PnS)(PMe3) (7). Dissociation of PMe3 ligands induces transformation of 1 to Ni(PpS)(PMe3)(2) (8) and Ni(PpS)(2). Crystal and molecular structures are given for 1, 5- 8, and dynamic solution spectra (NMR, EPR) are discussed. (C) 2009 Elsevier B.V. All rights reserved.
