The mechanism of the thermal rearrangement of substituted N-acyl-2,2-dimethylaziridines 1 has been studied using quantum chemistry methods. Geometries of reactants, transition states and products have been optimized at the B3LYP/6-311++G(2d,2p) level. Relative energies for various stationary points
## Abstract The kinetics of aminolysis of several substituted phenyl acetates by imidazole is studied in aqueous medium at 20Β°C and an ionic strength of 0.1 M (KCl). By following the leaving groups spectrophotometrically (Ξ»~max~ = 272β401 nm), under excess free imidazole, pseudoβfirstβorder rate co
The photochemical behaviour of 2-methyl-5-nitro-I H-imidazoles 1 in water-containing solutions has been studied. In a first reaction step, the photorearrangement of 1 yields 2-methyl-2-imidazoline-4,5-dione-4-oximes 2. Hydrolysis of 2 and subsequent elimination of water from a supposed intermediate
