Bernskoetter, Wesley H.,Tyler, Brian T.
, p. 520 - 527 (2011/03/21)
A zerovalent molybdenum complex, [(Ph2PCH2CH 2)2PPh]Mo(C2H4)(N2) 2, was found to promote coupling of CO2 and ethylene to afford a molybdenum(II) acrylate hy

The electrochemical reduction of the 15-electron molybdenum(III) complex , dpepp = Ph2PCH2CH2P(Ph)CH2CH2PPh2, has been studied in the presence of PPh3 under argon and under molecular nitrogen.The primary reduction of the trichloride involves a reversible single-electron transfer to give the unstable 16-electron molybdenum(II) anion -.Loss of chloride from this anion prior to or following further electron transfer provides two principal pathways to molybdenum(0) products, 6-C6H5PPh2)(dpepp)> under Ar or cis- under molecular nitrogen, a relatively high potential via molybdenum(I) solvated intermediates and a low potential pathway via trans-.The cis-dinitrogen complex is unstable on the preparative timescale, small amounts of trans- are formed, presumably by isomerisation, but the major product is the η6-arene complex.
Modification of silicon and carbon electrodes with methacrylamide polymers containing covalently attached molybdenum dinitrogen complexes
DuBois, Daniel L.
, p. 2047 - 2052 (2008/10/08)
Methacrylamide polymers with pendant monodentate, bidentate, and tridentate phosphine ligands (poly-P1, poly-P2, and poly-P3, respectively) have been synthesized. These polymers react with Mo(N2)2(PPh2Me)4 to form polymers with bound molybdenum dinitrogen complexes. Similarly, MoCl3(THF)3 reacts with poly-P3 to form MoCl3(poly-P3). These polymers have been used to modify silicon and carbon electrodes. These electrodes have been characterized by cyclic voltammetry and FT-IR spectroscopy. The redox chemistry of electrodes modified with Mo(N2)2(poly-P3)PPh2Me and Mo(N2)2(poly-P2)2 on silicon and carbon electrodes closely parallels that observed for their solution counterparts. However, reduction of MoCl3(poly-P3) and MoCl3(poly-P2)2 on silicon and carbon electrodes does not lead to formation of polymer-bound molybdenum dinitrogen complexes.
