Abstract

A two-step procedure for the synthesis of cationic organometallic complexes containing the robust cis-{Mo(NNRPh)2}2+ core (R = Me, Ph) is reported. The reaction of silver triflate, AgOTf (OTf-= CF3SO3-), with an equimolar amount of [Mo(NNMePh)2Cl2(PPh3)2] (1) or [Mo(NNPh2)2Cl2(PPh3)] (2) (in the presence of 1 equiv of PPh3) in CH2Cl2/CH3CN yields ionic intermediates formulated as [Mo(NNRPh)2Cl(PPh3)2]+OTf - (R = Me, [3]+OTf-; R = Ph, [4]+OTf-), which give ionic products formulated as [(η5-C5H5)Mo(NNRPh)2(PPh 3)]+OTf- (R = Me, [5]+OTf-; R = Ph, [6]+OTf-) upon reaction with excess NaCp in THF. These compounds have been characterized by IR, UV-visible, and NMR spectroscopy and cyclic voltammetry. The molecular structure of [6]+OTf- has also been determined by X-ray diffraction.
