Process and intermediates for preparing a cyclohexylnitrile

摘要

A method for preparing a 1,4-dicarbonitrile cyclohexan-1-ol cyclohexane-1-ol of formula (C) by cyanohydrin homologation of a cyclohexanone precursor is disclosed, wherein the method comprises cyanohydrin homologation of a cyclohexanone of formula (D), wherein the homologation is carried out using an alkali metal cyanide salt or a trialkylsilyl cyanide, where Ar is an aromatic group.
