Vanadium appears to be the element that is most frequent (along with molybdenum) used in the catalyst formulations for oxidative dehydrogenation (ODH) of hydrocarbons and alcs. The ODH reaction in the presence of air has been extended for the preparation of vinylpyridines and vinylthiophenes using vanadium (and for comparison molybdenum) oxide catalysts. The efficiency of vanadium-magnesium oxide catalysts in the production of vinylpyridines and vinylthiophenes has been evaluated. A strong dependence of the yield and selectivity of the latter upon the vanadium (molybdenum) oxide loading and the conditions of heat treatment were observed In optimized reaction conditions V-Mg-O catalysts at â?450° ensured the formation of vinylpyridines and vinylthiophenes in 40-60% yield and 90% selectivity. In prolonged runs no visible changes in the performance of the catalyst were observed DTA-DTG, XRD, IR ESR, NMR methods have been used to detect the formation of species of V-Mg-O catalysts that appear to be responsible for the catalyst efficiency in the reactions under consideration. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Synthetic Route of C8H11N).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Synthetic Route of C8H11N
