Antarafacial-Antarafacial Cope Rearrangement
Thermal rearrangement of 2-thiabicyclo[ 3.2.0]hepta-3,6-diene-6,7-dicarbonitriles 1-3 to their 4,5-dicarbonitrile isomers 4-6 takes place at 110-140 "C in yields of 82-84%. The reactions are first order with rates almost independent of the polarity of the solvent. Activation parameters (m = 120-140 kJ mol-' and AS* = 0 J K-l mol-') are in agreement with a concerted symmetry-allowed antarafacial...
متن کاملHow Cells Cope with Obesity
Currently, more than 2.7 million American adults are diagnosed as obese each year. Many of these people suffer from a disorder known as metabolic syndrome, which includes symptoms like hypertension and elevated blood cholesterol.

متن کاملA Theoretical Investigation of Kinetics and Mechanism of Aza-Cope Rearrangement
A theoretical study of the kinetic and mechanism of 3-aug-Cope rearrangement in gas phase was performed usingDET methods at B3LYP levels of theory with 6-3114iG(d,p) bass set at 298.I5K. Equilibrium moleculargeometries and harmonic vibrational frequencies of the reactant, transition state Did product were calculated. Then,rate constant and activation thermodynamics parameters were calculated an...
