| Hazard Information | Back Directory | [Description]
2-Methyleneglutaronitrile [1572-52-7], acrylonitrile dimer, 2,4-dicyano-1-butene, 2- methylenepentanedinitrile, NCC2H4C (=CH2) CN, is a colorless liquid slightly miscible with water, ethanol, acetone and benzene, immiscible with hexane. | [Chemical Properties]
Colorless liquid.Slightly soluble in water; insoluble in aliphatic andalicyclic hydrocarbons, soluble in aromatic hydro-carbons and polar organic solvents. | [Synthesis Reference(s)]
Tetrahedron Letters, 28, p. 4591, 1987 DOI: 10.1016/S0040-4039(00)96573-0 | [Synthesis]
2-Methyleneglutaronitrile is obtained by dimerization of acrylonitrile in the presence of a metal halide and a tertiary amine. Its hydrogenation yields 2-methylglutaronitrile, which in turn can be converted into 3-methylpyridine. |
