Abstract

Mo 0 dinitrogen complexes bearing electron-rich mono- and bidentate phosphines can be synthesized in good yields from inexpensive and readily accessible MoCl 5 via a one-step mild reduction with Mg metal. trans-[(N 2) 2Mo(PMePh 2)(PPh(CH 2CH 2PPh 2) 2)] can also be obtained via this strategy. However, in the presence of tri- and tetradentate ligands that are sterically restrictive, the analogous reduction leads to either (η 6-arene) formation or [Mo(multidentate phosphine) m] n oligomer complexes that have no dinitrogen ligands. One such η 6-arene complex, where the Mo 0 center is ligated by 1,1,1-tris(diphenylphosphinomethyl)ethane, was isolated and characterized via X-ray crystallography.
