摘要:
Reductive carbonylation of rhodium(III) chloride complexes, commercial RhCl3 center dot nH(2)O neutralized with BaCO3, (Me2NH2)(2)[RhC](5)(DMF)], (PPh4)[RhCl4(H2O)(2)], RhCl3(DMF)(3), RhCl3(CH3CN)(3), RhCl3(CH3CN)(2)(DMF), [Rh(CO)(2)Cl](2), and rhodium(I) complex, Rh(PPh3)(3)Cl, by N,N-dimethylformamide (DMF) is studied. The data obtained support the conception of direct carbonyl group transfer from DNIF molecule to the Rh metal center. The mechanistic scheme of carbonylation process is refined and discussed with regard of new experimental results. (c) 2006 Elsevier B.V. All rights reserved.
