A DFT-assisted mechanism for evolution of the ammoxidation of 2-chlorotoluene (2-CLT) to 2-chlorobenzonitrile (2-CLBN) over alumina-supported V2O5 catalyst prepared by a solution combustion method

Publikováno v: Journal of Catalysis. 345:245-257
Ammoxidation of 2-chlorotoluene (2-CLT) has been carried out over vanadates and supported vanadates in the temperature range 350–450 °C. The catalysts were characterized by XRD, XPS, FT-IR, and Raman and surface area measurement. A maximum yield o

Mechanism evolution for the oxidative dehydrogenation of ethyl benzene to styrene over V2O5/TiO2 catalyst: computational and kinetic approach
Autor: Manohar Singh Batra, Prabhakar Sharma, Rajendra Prasad, Rajeev Dixit, Reena Dwivedi
Publikováno v: RSC Advances. 5:39635-39642
A kinetic study of the oxidative dehydrogenation of ethylbenzene has been performed in a differential flow reactor over a V2O5/TiO2 catalyst. The partial pressures of ethylbenzene and oxygen were varied and rates were measured for the formation of st

Publikováno v: Tetrahedron: Asymmetry. 5:935-948
The synthesis of novel optically active crown ethers derived from (1 R )-(+)-camphor is described. The mechanism of their catalytic effect upon the Michael addition of phenylacetate to acrylate is discussed in terms of kinetic vs . thermodynamic cont

On the diastereoselectivity of cyanide addition to β-hydroxyketones: One-pot synthesis of syn β-hydroxycyanohydrins and anti 2,4-dihydroxyamides
Autor: Ernesto Brunet, Francisco J. Aguilar, Manohar Singh Batra
Publikováno v: Tetrahedron. 50:8169-8184
The intrinsic stereoselectivity of the cyanide addition to β-hydroxyketones in the presence of 18-crown-6 or ZnI2 is lower than that previously reported. However, the reaction bears a practical value in that syn β-hydroxycyanohydrins and anti 2,4-d

The diastereoselective preparation of syn-β-hydroxycyanohydrins by addition of cyanide to β-hydroxyketones with dimethyldicyanosilane
Autor: Ernesto Brunet, Manohar Singh Batra
Publikováno v: Tetrahedron Letters. 34:711-714
The addition of cyanide with Me 2 Si(CN) 2 to β-hydroxyketones (R 1 CHOH-COR 2 , R 1 = R 2 = alkyl) took place with high diastereoselectivity ( > 95% d.e.) and reasonable overall isolated yield (60%). The syn configuration of the produced β-hydroxy
