Synthesis and a Multinuclear NMR Spectroscopic Study of Some Mo(CO)5(PPh2XR) (X = O, NH; R = 1-4 Carbon Alkyls) Complexes. Steric Effects on 31P and 95Mo Chemical Shifts

Academic Article


  • The syntheses and multinuclear NMR spectroscopic data for a series of Mo(CO) (PPh XR) (X = O, NH; R = 1-4 carbon alkyls) complexes is presented. The steric effect of substitution at the α carbon of the R groups is shown to have an effect on the chemical shifts of the aromatic C(l) C, P, and Mo resonances but not upon the chemical shifts of the carbonyl C and O resonances. In addition, the good correlation observed between the chemical shifts of the Mo and aromatic C(l) C resonances indicates that in the Mo(CO) (PPh XR) complexes, the Mo and aromatic C(l) C resonances are similarly affected by changes in the R group. © 1983, American Chemical Society.
