KINETIC-STUDIES OF LIGAND SUBSTITUTION-REACTIONS AND GENERAL-BASE CATALYSIS IN AMINE-LIGAND EXCHANGE PROCESSES FOR GROUP-6B METAL-CARBONYL AMINE DERIVATIVES - KINETIC AND SPECTROSCOPIC EVIDENCE FOR HYDROGEN-BONDED INTERMEDIATES uri icon

abstract

  • The decomposition and ligand substitution reactions of group 6B metal pentacarbonyl piperidine derivatives with phosphines have been studied. The reactions are catalyzed by the Lewis bases OP(n-C4H9)3 and tetrahydrofuran (THE). It is concluded that the results are best accounted for in terms of hydrogen-bonded intermediates in the general-base catalysis with the mechanism for catalysis being closely analogous to a dissociative interchange (Id) pathway. The intermediates have been observed and characterized by infrared spectroscopy. 1981, American Chemical Society. All rights reserved.
