(η⁴-Tetracyclone)(CO)3Ru and <(η⁴-tetracyclone)(CO)2Ru>2 are cataylst precursors in the direct oxidation of primary alcohols to esters.Their use without a H-acceptor in an open reaction system leads to bimolecular dehydrogenation of primary alcohols to esters and also of secondary alcohols to ketones with evolution of H2.The strucutre of (η⁴-tetracyclone)(CO)2(H)2Ru was assigned to a reaction intermediate observed during the catalysis.A catalytic cycle is proposed.
