C 31 Catalytic effect of nanosized metal oxides on the Hantzsch reaction [Text] / O. V. Fedorova, O. V. Koryakova, M. S. Valova, I. G. Ovchinnikova, Yu. A. Titova, G. L. Rusinov, V. N. Charushin // Kinetics and Catalysis. - 2010. - Vol. 51, № 4. - P566-572 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): METAL OXIDES -- HANTZSCH REACTION -- ALUMINUM OXIDES Аннотация: The effect of nanosized copper and aluminum oxides, which have a higher sorption capacity than that of bulk samples, on the Hantzsch reaction was studied. The adsorption of starting benzaldehydes and ethyl acetoacetate on the surface of copper and aluminum nanooxides resulted in the activation of these molecules and accelerated the Hantzsch reaction. In addition, considerable activation of ammonia and intermediates (chalcone and enamine) on the surface of aluminum nanooxide facilitated an increase in the rate and selectivity of the process. The experimental results were used to develop a one-pot method for the preparation of nifedipine and nitrendipine \\\\Expert2\\nbo\\Kinetics and Catalysis\\2010, v. 51, N 4, p. 566-572.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): NANOOXIDE TiO2–SiO -- BIGINELLI REACTION -- ASYMMETRIC CATALYSIS Аннотация: The method for immobilization of chiral molecules (menthol and proline derivatives) on the mixed nanooxide TiO2–SiO2 surface has been developed. The synthesized nanocomposites were used as catalysts of the Biginelli reaction. It was shown that inactive chiral molecules, when covalently bonded to the nanooxide surface, acquired properties of a chiral inducer in the asymmetric Biginelli reaction. \\\\expert2\\nbo\\Catalysis Today\\2015, v.241, p.270.pdf |
