The Cope rearrangement of gem-dimethyl substituted divinylcyclopropanes.
The reactivity of a range of substituted divinylcyclopropanes towards the thermal Cope rearrangement has been examined. The effects of gem-dimethyl substitution on the cyclopropane, the alkene geometry, the relative stereochemistry of the cyclopropane and the steric and electronic effects of a range of functional groups were all examined, and the methods developed were used to synthesise a rang...
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...
متن کاملBET & ELF Quantum Topological Analysis of Neutral 2-Aza-Cope Rearrangement of γ-Alkenyl Nitrones.
The 2-Aza-Cope rearrangement of γ-alkenyl nitrones is a rare example of the neutral thermal 2-aza-Cope process that usually takes place with cationic species. During the rearrangement, a redistribution of bonds and electronic density occurs in one kinetic step. However, the introduction of substituents with different steric requirements and electronic features might alter the activation energie...
متن کاملLow pressure CO(2) to dimethyl carbonate by the reaction with methanol promoted by acetonitrile hydration.
CeO(2) catalysts catalyze the reaction of methanol with low pressure CO(2) to form dimethyl carbonate and the reaction was promoted by the combination with acetonitrile hydration over CeO(2).
متن کاملStereocontrolled synthesis of angularly substituted 1-azabicyclic rings by cationic 2-aza-cope rearrangements.
A new synthesis of 1-azabicyclic molecules having angular substitution is reported. This method can be employed to prepare a range of 1-azabicylic rings, including ones containing vicinal quaternary carbon centers and three contiguous stereocenters. [structure: see text]
