Abstract

1,143,484. Dimerization of unsaturated nitriles. NATIONAL DISTILLERS & CHEMICAL CORP. 25 Feb., 1966 [2 March, 1965], No. 8502/66. Heading C2C. Unsaturated α,γ-dinitriles are prepared by dimerizing acrylonitrile or a #-substituted acrylonitrile under an inert atmosphere in the presence of a solvent and an alkylaryl phosphine catalyst, other than a phosphine containing both a phenyl and a straight-chain alkyl group, having the formula (A)n(B)mP, where A is an aryl group, B is an alkyl or cycloalkyl group and m and n are integers greater than 0 with m+n=3. The preferred catalyst is phenyldicyclohexyl phosphine. Specified solvents include aromatic hydrocarbons, aliphatic ketones, ethers and esters, cyclic ethers and alkanols. A polymerization inhibitor may be included in the reaction mixture. An example describes the preparation of 2-methylene glutaronitrile from acrylonitrile.
