Chen, Feng published the artcileHydrogenation of Pyridines Using a Nitrogen-Modified Titania-Supported Cobalt Catalyst, Category: piperidines, the publication is Angewandte Chemie, International Edition (2018), 57(44), 14488-14492, database is CAplus and MEDLINE.
Heterogeneous recyclable catalysts were prepared by pyrolysis of Co(OAc)2, melamine, and titanium dioxide; in their presence, pyridines underwent chemoselective hydrogenation to piperidines in water under acid-free conditions. The resulting materials show an unusual nitrogen-modified titanium structure through partial incorporation of nitrogen into the support. The catalyst was also used for the preparation of N-isopropylpiperidines by hydrogenation of pyridines in isopropanol.
Angewandte Chemie, International Edition published new progress about 39546-32-2. 39546-32-2 belongs to piperidines, auxiliary class Piperidine,Amine,Amide, name is Piperidine-4-carboxamide, and the molecular formula is C6H12N2O, Category: piperidines.
