Delta-cyano-valeric esters - prepd by reaction of 2-oximino-cyclohexanone with a carboxylic acid anhydride or a ketene and an alcohol

摘要

gamma-Cyanovaleric esters are prepd. by reacting 2-oximinocyclohexanone with a carboxylic acid anhydride and/or a ketene as acylating agent and an alcohol of formula R'OH (where R' is aliphatic, cycloaliphatic or araliphatic). High yields of prod. with improved purity, are obtd. simply and cheaply. Used as inters. for pesticides, dyes, plastics etc.
