Molybdenum Carbonyl Complexes Bearing PN Ligands Based on 2‐Aminopyridine

Abstract

Abstract Molybdenum complexes of the general formula Mo(PN)(CO) 4 containing both achiral and chiral phosphorus‐nitrogen donor bidentate ligands based on 2‐aminopyridine were prepared and characterized by their NMR and IR spectra. The oxidative addition of allyl bromide to Mo(PN)(CO) 4 was studied with PN = N ‐(diisopropylphosphanyl)‐2‐aminopyridine (PN‐ i Pr). X‐ray structures of representative compounds were determined. The mechanism of the oxidative addition of allyl bromide to Mo(PN‐ i Pr)(CO) 4 was analyzed by DFT/B3LYP calculations. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
