abstract

  • The reaction of the oxalate anion, C2O42-, with W(CO)5(solvent) results in rapid formation of W(CO)4(2-C2O4)2- (1). On the basis of kinetic parameters previously determined for a series of W(CO)5O2CR-derivatives, complexes containing a carboxylate ligand with a good electron-releasing group, R, are subject to facile displacement of a cis CO. Indeed, in the case of the predicted initial product, W(CO)5(1-C2O4)2-, this displacement is anticipated to occur readily, as was observed, with t1/2 = 23 s. Complex 1 reacts with a second molecule of W(CO)5(solvent) to form the stable dimer W2(CO)8(2-C2O4)2- (2). 1992, American Chemical Society. All rights reserved.
