Description

Reaction of 2-pyridineacetonitrile (II) with aldehydes in the presence of sodium hydroxide or piperidine in ethanol gives α-alkylidene-2-pyridineacetonitrile (V). II does not react with ketones under the same condition but does react with benzophenone in the presence of sodium amide to give α, α-diphenyl-2-pyridineethanol (IX). II easily transits to α-acyl-2-pyridineacetonitrile (X) by reaction with acid halides. Catalytic reduction, hydrolysis, and Grignard reaction of V are also described.
