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 Influence of the medium on hydrogenation of 2-methylglutaronitrile. Selective access to 2-methylpentane diamine or β-picoline after dehydrogenation, published in 1995, which mentions a compound: 4553-62-2, Name is 2-Methylglutaronitrile, Molecular C6H8N2, Application In Synthesis of 2-Methylglutaronitrile.
A conference. The 2-methylglutaronitrile (I) is obtained as a byproduct of the important adiponitrile production It, nevertheless, gives rise to interesting chem. transformations. In particular, its hydrogenation can produce 2-methylpentanediamine, a substitute for hexamethylenediamine in polyamide or polyurethane compounds The 3-methylpiperidine, also produced by hydrogenation of I, can be an interesting intermediate for β-picoline production involved in the synthesis of PP vitamin. Using Raney nickel as the catalyst, hydrogenation reactions were performed in various liquid phase compositions 2-Methylpentanediamine was obtained very selectively. The reaction product can be used itself as solvent. Addition of dry ammonia in ethanol in the place of isopropanol / KOH or NaOH medium leads to a mixture of 2-methylpentanediamine, 3-methylpiperidine and some heavy byproducts. This mixture can be cyclized and dehydrogenated to β-picoline (3-methylpyridine) on a special and very efficient Pd/SiO2 catalyst. The two processes have been patented by Rhone-Poulenc.
