In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Electrochemical reduction of 2-methylglutaronitrile on deposited electrodes in aqueous media, published in 1985-06-30, which mentions a compound: 4553-62-2, Name is 2-Methylglutaronitrile, Molecular C6H8N2, Quality Control of 2-Methylglutaronitrile.
H2N(CH2)3CHMeCH2NH2 was obtained in 40-60% yield by the electrochem. reduction of NCCH2CH2CHMeCN using deposited nickel black and palladium black cathodes under different conditions. Various synthetic parameters were standardized. The results obtained from various reduction experiments are discussed.
