Arene–tungsten chemistry: bis(arene)tungsten hydride derivatives; co-condensation of tungsten atoms from an electron gun source with aromatic hydrocarbons

Abstract

Co-condensation of tungsten atoms from an electron gun source with benzene, toluene, or mesitylene yields bis-(arene)tungsten compounds [(η-C₆H₃R₃)₂W](R = H and/or Me) which are reversibly protonated by dilute acids to give the cations [(η-C₆H₃R₃)₂WH]⁺(R = H and/or Me).
