Abstract
An a ,b -olefinically unsaturated nitrile or ester is reductively dimerized by bringing an alkali metal or alkaline earth metal amalgam into interaction with a reaction medium containing the nitrile or ester, a salt that provides alkylated cations in the reaction medium, and an agent such as water or an alcohol that can donate active hydrogen and co-operates with the amalgam to provide an amalgam reduction system. Suitable starting materials are acrylonitrile and alkyl - substituted acrylonitriles ("alkyl" having up to 4 carbon atoms and including alkenyl and alkynyl with the unsaturation not adjacent to the acrylonitrile double bond), and mono- and di-carboxylate esters. The salts used may be alkylated ammonium, phosphonium or sulphonium salts. Inorganic salts such as CrCl3 or Na2CrO4 may be added as promoters. Polar solvents, such as dioxane, acetone, dimethylformamide or ethylene glycol, and polymerization inhibitors, such as N1N-dimethyl p-nitrosoaniline, may be present. When using alkali metal amalgams the constant addition of an acid or CO2 is required. Ambient temperature is preferred. Examples prepare adiponitrile, 3,4-dimethyl adiponitrile and diethyl adipate.
