Notes:
The effects of one-bond and two-bond 2H, 13CO and C18O isotope shifts on 51V shielding in various carbonyl-Cp-vanadium complexes (Cp = n5-cyclopentadienyl) are reported and discussed with respect to the sensitivity of 51V shifts to bond extensions, and the rovibrationally averaged values of such bond extensions. These isotope effects provide some insight into the bonding situation in these complexes. It is shown that the rate-determining step in the reaction between V(CO)6 and C5H5D, which leads to CpV(CO)4, is not subject to a kinetic isotope effect. The deuterium solvent isotope effects on 51V shielding in [V(CO)6]- and [VO4]3- are also investigated.
