Molybdenum-95 NMR chemical shifts are reported for a series of Mo(0) compounds of the type Mo(CO)4(pip)2-nLn (n=1,2; L=substituted pyridine ligands).The δ(95Mo) values correlate well with the pKa values for the substituted pyridines; for the n=1 series, Δ(95Mo) ranges from -1053 ppm (pKa=1.86 for 4-CN) to -1120 ppm (pKa=9.61 for 4-NMe2).The effects of solvent polarity and some in situ reactivity studies are described and the nature of the Mo-L bond compared to that with piperidine and some other ligands is discussed.
