Title:
CATALYTIC OSMIUM-ASSISTED OXIDATIVE CLEAVAGE OF OLEFINS
Document Type and Number:
WIPO Patent Application WO2003060852
Kind Code:
A3
Abstract:
An osmium-assisted process for the oxidative cleavage of oxidizable organic compounds such as unsaturated organic coumpounds, including alkenes and olefins into aldehydes, carboxylic acids, esters, or ketones. The process uses a metal catalyst comprising osmium and a peroxy compound selected from the group consisting of peroxymonosulfuric acid and salts thereof to oxidatively cleave the oxidizable organic compound. In particular, the process enables aldehydes, carboxylic acids, esters, or ketones to be selectively produced from the corresponding mono-, 1,1-di-, 1,2-di-, tri-, or tetra-substituted olefins in a reaction that produces the result of ozonolysis but with fewer problems. The present invention further provides a process for oxidizing an aldehyde alone or with the osmium in an interactive solvent to produce an ester or carboxylic acid.
