Abstract
Abstract Oxygenated organic compounds, e.g. esters, aldehydes, and amides, are prepared by reacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt or ruthenium carbonyl and a promoter ligand. The promoter ligand is selected from the group consisting of heterocyclic nitrogen oxide compounds and phosphorus or sulfur oxides. These reactions are carried out under relatively mild conditions of temperature and pressure.

Claim 1
Independent Claim
114 words
A process for the production of methylbetacyanopropionate comprising contacting acrylonitrile with carbon monoxide and methanol in the present of a catalyst comprising cobalt carbonyl and a promoter ligand having the following structure: ##STR8## wherein R 1 , R 2 , R 3 , R 4 and R 5 are each independently selected from the group consisting of: (1) H; (2) C 1-10 alkyls; (3) (CH 2 ) q OH wherein q is 0-10; (4) ##STR9## wherein s is 0-10; and (5) O(CH 2 ) t CH 3 wherein t is 0-10; and wherein R 1 and R 2 may comprise a five to eight membered carbocyclic fused ring optionally substituted with C 1-10 alkyls.
