Description

General description

Cyclohexanone is a cyclic ketone mainly used as an intermediate in the synthesis of nylon.

Application

Cyclohexanone may undergo asymmetric Michael addition with aryl and alkyl nitroolefins in the presence of pyrrolidine-urea based catalysts to form the corresponding adducts. It may also be used in the synthesis of a wide range of compounds such as adipic acid, 2-(hydroxy(phenyl)methyl)cyclohexanone, 2-allylcyclohexan-1-one, tetrasubstituted propargylamines and N-cyclohexyl-benzyl amine derivatives.
