The reaction of 1-chloro-2-nitrobenzene with dinitrogen pentoxide in dichloromethane catalysed by H-faujasite zeolites F-712, F-720, F-780 and F-901, giving 1-chloro-2,4-dinitro- and 1-chloro-2,6-dinitrobenzene in approximately 30∶1 ratio, is a kin

Anisole can be nitrosated in good yield under the acidic and anaerobic conditions previously reported for methylbenzenes. The product, 4-nitrosoanisole, is slowly converted into 4-nitrosophenol in acetic–sulfuric acid mixtures. The decrease in the

The title reactions give good yields with m-xylene, and modest yields with toluene and o-xylene which are successfully directly nitrosated for the first time. The advantages of purging with nitric oxide are demonstrated and discussed. The kinetics ha

The reactions of 2-nitrotoluene, 1-chloro-2-nitrobenzene, and 1-chloro-4-nitrobenzene with dinitrogen pentoxide in dichloromethane at 0 °C are strongly catalysed by some zeolites notably H-Faujasite-720, catalysis by which is investigated in detail.

The acidity dependencies of the equilibria between nitrous acid and nitrosonium ion, and between nitrate ion and nitric acid in aqueous trifluoroacetic acid (TFA) have been investigated. The decomposition of nitrous acid in air-saturated aqueous TFA

3-Phenyloxetane reacts initially almost entirely by ortho and para aromatic nitration. This is followed by oxetane ring-opening to give the corresponding 2-arylpropane-1,3-diol dinitrates. The oxetane ring-opening reactions, and the reaction of 7-oxa

Kinetics and products of reaction of 4-R-styrenes (R = Me, H, Cl, CF3, NO2) with nitric acid in dichloromethane are reported. Reaction occurs in the alkene group and aromatic nitration is insignificant. With increasingly electron-withdrawing substitu

The reactions of 3-phenyloxetane 1, 3-(4-nitrophenyl)oxetane 5 and 3,3-pentamethyleneoxetane 7 with nitric acid in dichloromethane or trichloromethane under anhydrous conditions have been investigated. Quantitative conversion to 2-substituted propane

Free energies, enthalpies and entropies of activation have been measured for the ring–chain tautomeric equilibria existing in imidazolidine, hexahydro-pyrimidine and -diazepine ring systems under acid- catalysed conditions in a solvent consisting o

The competition between oxidation to the corresponding benzoic acid and nitration in the aromatic ring of some substituted benzaldehydes has been probed by kinetic and product studies. Nitrodeformylation was not detected. 4-Carboxybenzaldehyde is nit
