Expedient Acylations of Primary and Secondary Alkyl Cyanides to α-Substituted β-Ketonitriles
摘要:
Primary and secondary cyanides are efficiently acylated with N-acylbenzotriazoles 3a-f (derived from a variety of acids) to afford the corresponding alpha-substituted beta-ketonitriles 5a-r in 67-96% yields.

A bis(phenylacetyl)benzene compound is reacted with a sulfoxide compound and a halide in the presence of an acid and an organic solvent. Also, a bis((-ketonitrile) compound is reacted in an acidic environment in the presence of water, a halide and a sulfoxide compound. It is thereby possible to produce bisbenzil compounds at a high yield and with high productivity.
