Synthesis and multinuclear NMR and mass spectroscopic study of some Mo(CO)5(PPh)2XR) (X = O, S, NH; R = alkyl, aryl, Me3Si) complexes. Chemical shift correlations with cis-Mo(CO)4(PPh)2XR)2 chemical shifts

Abstract

  • The synthesis of a series of Mo(CO) (PPh XR) complexes are reported. The complexes have been characterized by multinuclear NMR-, infrared,-, and mass spectroscopy. Chemical shift correlations between the carbonyl C and O, P-C C, P and Mo chemical shifts are demonstrated to depend upon the similarity in size of the XR groups. Fair to excellent correlations between these chemical shifts and similar chemical shifts of some cis-Mo(CO) (PPh XR) complexes are reported and indicate that the steric effect the PPh XR ligands are similar in the two sets of complexes. © 1984. 5 2 4 2 2 2 13 17 13 31 95
