Abstract

Disclosed is an effective method for producing an ester compound at a reaction temperature lower than that of conventional methods, and with a high yield, even when inexpensive formic acid ester is used as a starting material. A method for producing an ester compound, the method comprising the step of reacting an organic compound having at least one unsaturated carbon bond in the molecule, and a formic acid ester in the presence of a catalyst system containing: a ruthenium compound; a cobalt compound; and a halide salt.
