A High-Yielding Preparation of -Ketonitriles

Abstract:
Ketonitriles are important precursors for a wide variety of biologically active heterocycles. A facile procedure for the high-yielding acylation of
nitrile anions with unactivated esters to provide -ketonitriles is reported. The procedure is successful with enolizable and nonenolizable esters as
well as hindered nitrile anions.
Note:...."while decyanation provides ketones. (5.).....seems like they used 48% hydrobromic acid, reflux, to remove the CN

Interested thread about nitriles and a variety possibilityes
for heterocyclic ketosynteses. I think easy chemical (acetonitril..) and salt with the -CN group are suitable for
heterocyclic ketosynteses and reactions with esters.
