2-Adamantyl substituted quinine-squaramide catalyzed aza-Friedel–Crafts reaction of <italic>N</italic>-carbamate isatin ketimines with naphthol afforded chiral isatin-derived 1,3-aminonaphthols excellent enantioselectivity up to greater than 99% and quantitative yield.
Bifunctional squaramide catalyzed asymmetric Mannich reaction of alpha-azido ketones and isatin derived ketiminines were established for the first time with high stereoselectivity. Adducts are valuable synthons optically active heterocycles.
In this study, we investigate the kinetic and thermodynamic aspects of thermal cracking reactions short paraffin chains by density functional theory (DFT) methods. The have been modeled for a series shorter unbranched alkanes at 673 K following free-radical mechanism. Benchmark calculations carried out with different functionals (B3LYP, M06-2X, PBE0, BMK, B3PW91) basis sets (6-31G(d,p), 6-311+G(d,p)) to determine most suitable DFT method, results were compared available experimental data....
Highly acidic crude oils are abundant at low cost, therefore they considered as good alternatives to typical oils, provide a supply for the increasing demand transportation fuels. However, extremely corrosive, therefore, isolation of acids from oil and on-the-spot decomposition is major concern. A wide variation compounds present in these majority known be naphthenic (NAs). Isolated NAs can co-processed by blending them into feed streams furnaces refinery/petrochemical sites operating...
Highly acidic crude oils are abundant at low cost; therefore, they considered as good alternatives to typical oils, provide an additional supply for the increasing demand transportation fuels. However, extremely corrosive; isolation of acids from oil and on-the-spot decomposition is a major concern. A wide variation compounds present in these oils; most known be naphthenic (NAs). Isolated NAs can processed furnaces operating different temperatures refinery/petrochemical sites. In this study,...
