Abstract

Some common onium salts catalysed selective urethane production from amines and alkyl halides in supercritical carbon dioxide, which acted not only as an alternative to organic solvents but also as a phosgene replacement; the reaction efficiency was 50100 times higher than that attained in heptane.
