Liquid metal alkyls are strong Lewis acids and bases and useful solvents in which to conduct organometallic reactions. Cp2ZrMe2 undergoes rapid methyl exchange with pure Me3Al but reacts with EtAlMe2 in Me3Al to form Cp2Zr(mu-CH3)(mu-CH2CH2)AlMe2. Neat R3Al reagents in which R has a hydrogen atom produce solvated Cp2ZrH2 derivatives. The gas-phase reaction of Cp2ZrCH3+ with Me3Al, studied by ion cyclotron resonance spectrometry, produces an ion formulated as Cp2Zr(mu-CH2)2Al+.
