Multinuclear NMR spectroscopic study of a series of Mo(CO)5(PPh2OC6H4-p-R) complexes. The relationship between chemical-shift correlation and the polar and resonance properties of the R group

Academic Article


  • The multinuclear NMR spectroscopic data of a series of Mo(CO) (PPh OC H -p-R) (R = alkyl, alkoxy, aryl, halo, etc.) complexes are presented. Since a change in the para-R group has little effect on the cone angle of the phosphinite ligands, good to excellent correlations are observed between the chemical shifts of many of the C, O, P, and Mo resonances. Good correlations are also observed between the chemical shifts and the Taft σ ° and σ parameters. A linear relationship between the degree of correlation observed between the chemical shifts of any two nuclei and the differences in the response of the chemical shifts to polar and resonance effects has been developed. © 1984. 5 2 6 4 R 1 13 17 31 95
