Abstract: Reduction using sodium amalgam of the complex [Mo(η-C6H6)(dmpe)(η-C3H5)]+(dmpe = Me2PCH2CH2PMe2) in the presence of the olefins L = ethylene, propene, or cyclopentene gives the neutral η2-olefin compounds [Mo(η-C6H6)(dmpe)L]. The η-ethylene compound readily protonates forming the hydrido-cation [Mo(η-C6H6)(dmpe)(η-C2H4)H]+. Treatment of this with the tertiary phosphines PR3, where R3= Me3 or Me2Ph, gives the η-ethylbenzene compounds [Mo(η)-C6H5Et)(dmpe)(PR3)H]PF6. The new compounds trans-[Mo(η-C6H6)(dmpe) H2], [{Mo(η-C6H6)(dmPe)}2(µ-dmpe)], [(Mo(η-C6H6)(dmpe)H}2(µ-dmpe)][PF6]2, [Mo(η-C6H6)-(η-C3H5)(PMe3)Cl], [Mo(η-C6H6)(PMe3)3], and [Mo(η-C6H6)(PMe3)3H]PF6 are also described.
