The Pinner reaction refers to the acid catalysed reaction of a nitrile with an alcohol to form an imino ester salt (alkyl imidate salt); this is sometimes referred to as a Pinner salt. The reaction is named after Adolf Pinner, who first described it in 1877. Pinner salts are themselves reactive and undergo additional nucleophilic additions to give various useful products: • With an excess of alcohol to form an orthoester WebHighly direct oxidative cyanation of alcohols provides a promising synthesis route for the cyanide-free synthesis of organic nitriles.
