Synthesis and characterization of arene, mono-and dihydrido-arene, monohydrido-cyclopentadienyl, and phosphite complexes of molybdenum containing the tridentate ligand PhP (CH2CH2PPh2)2

The reduction of [MoCl3(TRI)], where TRI = PhP(CH2CH2PPh2)2, with sodium amalgam in benzene, toluene or anisole resulted in the formation of the corresponding [Mo(η6-arene) (TRI)] complex. Each complex displayed a reversible one-electron oxidation in the cyclic voltammogram at ～ - 1.0 V versus the ferrocenium/ferrocene couple at 0.0 V, corresponding to the oxidation of Mo(0) to Mo(1+). A second pseudo-reversible oxidation occurred at ～0.7 V more positive. Monoprotonation of the arene complexes with CF3COOH in THF resulted in the isolation of [Mo(H)(η6-arene)(TRI)][CF3COO] (δ(MoH) ～ - 6 ppm). In neat CF3COOH or HBF4, evidence of diprotonation of the arene complexes was observed in the 1H NMR spectra. Upon work-up, only the monoprotonated product was isolated. [Mo(TRI)(P(OMe)3)] was formed by the reduction of [MoCl3(TRI)] in the presence of a small excess of P(OMe)3. Attempts to prepare [Mo(TRI)(PMe3)3] by a similar method resulted in a product that readily absorbed N2 to form fac-[Mo(N2)(TRI)(PMe3)2]. Yellow [Mo(H)(η5-C5H5)(TRI)] was formed by (i) the reduction of [MoCl3(TRI)] with sodium amalgam in the presence of cyclopentadiene, or (ii) heating fac-[Mo(N2)(TRI)(PMe3)2] with cyclopentadiene in heptane, or (iii) heating trans-[Mo(N2)2(TRI)(PPh3)] with cyclopentadiene in THF.

Synthesis and characterization of low valent complexes of molybdenum containing the tridentate ligand PhP(CH2CH2PPh2)2(TRI)

Reduction of with sodium amalgam in the presence of potential ligands results in the formation of a series of new complexes containing η3-TRI.These include 6-C6H5R)(TRI) (where R = H, Me, MeO), 5-C5H5)(H)(TRI)>, (where R = Me, Et), and fac-.Protonation of the arene complexes results in the formation of both mono- and diprotonated complexes.Keywords: Molybdenum; Phosphine; Phosphite; Dinitrogen; η6-Benzene complex; η6-Arene complex.
