Coordination chemistry of aminoborylphosphanes. Crystal structure determinations of (iPr2N)2BP(H)SiPh3·Cr(CO)5 and [(iPr2N)2BP(H)]2SiMe2·W(CO)4
摘要:
The reactions of the aminoborylphosphanes, ((Pr2N)-Pr-i)(2)BP(H)SiPh3 (1), [((Pr2N)-Pr-i)(2)BP(H)](2)siMe(2) (2), and [((Pr2N)-Pr-i)(2)SP(H) Si(Me)(2)](2) (3) with M(CO)(5). NMe3 or M(CO)(4) (norbornadiene) (M = Cr, Mo, W) gave solid, crystalline adducts, three of which have been fully characterized. The molecular structures of ((Pr2N)-Pr-i)(2)BP(H)SiPh3. Cr(CO)(5) (4) and [((Pr2N)-Pr-i)(2)BP(H)](2)SiMe2 .W(CO)(4) (5') have been determined by single crystal X-ray diffraction techniques. Ligand 1 acts as a monodentate sigma donor ligand while 2 coordinates as a chelating phosphane. (C) 1999 Elsevier Science S.A. All rights reserved.
