<p>A method of cleaving ketones at a carbon-carbon bond adjacent to the ketonic carbon to produce a terminal carboxylic ester and a terminal oxime group, which comprises, nitrosating the ketone in the presence of a polar aprotic solvent and an alcohol. The products are useful intermediates, particularly as intermediates in the production of polyamides, and as solvents. A method of synthesizing epsilon -caprolactam from the intermediate omega -hydroximino hexanoate, produced by cleaving cyclohexanone, hydrogenating the intermediate omega -aminohexanoate ester and cyclizing the corresponding ester thus formed, to epsilon -caprolactam.</p> |
