Deboronation of HB(3,5-Me2C3HN2)3− in a reaction with [Re(O)Cl4]−, the X-ray crystal structures of [{Re(O)Cl(3,5-Me2C3HN2H)3}(μ-O){Re(O)Cl3(3,5-Me2C3HN2H)}] and [{Re(O)Cl2(3,5-Me2C3HN2H)2}(μ-O){Re(O)Cl2(3,5-Me2C3HN2H)2}]
摘要:
A modified synthetic route to [Re(O)(tp*)Cl-2] {tp* =HB(3.5-Me2C3HN2)(3)} from Re2O7 is described. The reaction between Bu4N[Re(O)Cl-4] and Ktp* affords, as its main product, the unsymmetrically substituted binuclear ore-bridged complex [{Re(O)Cl(3,5Me(2)C(3)HN(2)H)(3)}(mu-O) {Re(O)Cl-3(3,5-Me2C3HN2H)}] (1) together with some of the known symmetrically substituted isomer [{Re(O)Cl-2(3,5-Me2C3HN2H)(2)}(mu-O) {Re(O)Cl-2(3.5-Me2C3HN2H)(2)}] (2). Both isomers were characterised by single crystal X-ray diffraction studies of the CH2Cl2 solvates. (C) 1999 Elsevier Science S.A. All rights reserved.
