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.
