Abstract: The reaction mechanism between propadienylidene and methyleneimine was systematically investigated employing the second-order Møller–Plesset perturbation theory (MP2) method with the 6 – 31 + G* basis set. Geometry optimization, vibrational analysis, and energy property of the involved stationary points on the potential energy surface were calculated. The energies of the different spe...

The kinetics of the addition reaction at a solid interface for a model epoxy-amine system composed of monofunctionalized phenyl glycidyl ether and hexylamine was examined. The chemical character for the reaction of this system at the interface was the same as that in the bulk, while the physical nature was significantly different. Slowing down of the diffusion for the reactants in close proximi...

An unusual dehydroxymethylation has been observed in an acyclic primary alcoholic system. The relief of steric congestion is considered as the primary driving force in this reaction. 2006 Elsevier Ltd. All rights reserved. The nucleophilic additions of carbon nucleophiles to aldehydes or ketones are highly favourable processes. Nucleophilic addition of carbon anion to a carbonyl group is normal...

A convenient synthesis of benzyl-gamma-butyrolactone derivatives via intramolecular Michael addition reaction of nitro-substituted aryl allyl beta-ketocarboxylates is reported. The method features simple operation, mild reaction conditions and high efficiency.

As an electrophile, bromonitromethane was used as a versatile reagent in the synthesis of aminothiophenes and their derivatives as well as in the reaction with nucleophiles such as thiolates, sulphides, thiourea, thiocyanate, iodide and phosphorus based species [1]. Bromonitromethane contains only one carbon atom, therefore it is relevant to C-1 chemistry [2]. In chemical synthesis, it has two ...
