Linear esters, e.g., alkyl adipates, are facilely prepared by reacting an alcohol and carbon monoxide with a monoolefin, in the presence of cobalt, optionally hydrogen, and a tertiary nitrogen base, and in a reaction solvent which comprises a 5- or 6-membered monoheterocycle containing from 1 to 3 identical or different, non-adjacent oxygen and divalent sulfur heteroatoms, with the proviso that such heterocycle can also contain from one to two carbon-carbon double bonds, and, if a 5-membered heterocycle, can also contain a nitrogen heteroatom separated from an oxygen or sulfur heteroatom by at least one ring carbon atom and linked to one of the adjacent carbon atoms by a double bond. |
