Possible mechanisms of the carboxylation of olefins in the presence of CO are discussed. It is suggested provisionally that the catalytically active compound is Co hydrocarbonyl. It adds to the unsaturated bonds of the olefins with formation of intermediate compounds, which, in their turn, react with compounds containing mobile H atoms.
