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.
