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 Catalytic Hydrogenation of Substituted Quinolines on Co-Graphene Composites, published in 2021-12-21, which mentions a compound: 114527-53-6, Name is 1,2,3,4-Tetrahydroquinoline-3-carboxylic acid, Molecular C10H11NO2, Formula: C10H11NO2.
A set of 20 composites was prepared by pyrolysis of Co2+ complexes with 1,10-phenanthroline, melamine and 1,2-diaminobenzene. These composites were tested as the catalysts for the hydrogenation of quinolines. As shown by powder X-ray diffraction and TEM, the composites contained Co particles of several dozen nm sizes. The composition (elements content), Raman spectra X-ray photoelectron spectra parameters of the composites were analyzed. It was found that there was no distinct factor that controlled the yield of 1,2,3,4-tetrahydroquinolines in the investigated process. The yields of the resp. products were in the range 90-100%. The three most active composites were selected for scale-up and hydrogenation of a series of substituted quinolines. Up to 97% yield of 1,2,3,4-tetrahydroquinoline was obtained on a 50 g scale. Five representative substituted quinolines were synthesized on a 10-20 g scale using the Co-containing composites as the catalysts.
