Water soluble iron(III) porphyrins and phosphotungstic acid in an ionic liquid are effective catalysts for the H2O2 mediated oxidation of the CNOH bond in N-hydroxyarginine and other oximes. The carbonyl compounds generated as the oxidation products can be easily isolated from the reaction media. These systems serve as biomimetic models of nitric oxide synthase (NOS) and the catalyst immobilized in an ionic liquid can be easily recycled and reused.

Montmorillonite K10 has been used in the deprotection of different aromatic and aliphatic 1,3-oxathiolanes to the corresponding carbonyl compounds in 73 to 97% yields under mild and environmentally compatible conditions.

Organic models of flavoenzymes consist of a binding site covalently attached to a flavin derivative acting as the catalytic site.The earlier reported synthesis of such a model using α-cyclodextrin as the binding site proved to be difficult to reproduce wi

The characteristics of aromatic nucleophilic substitution with activation by the iminium group in the iminium derivatives of p-alkoxy- and p-halogenobenzaldehydes were investigated.They are determined by the concurrent addition of the nucleophilic agents at the C=N multiple bond.The activating effect of the iminium group depends on the nature of the leaving group, the solvent, the substituent in the benzene ring, and the nature and concentration of the protonating agent.The action of heat on p-methoxybenzylidenemethylamine with a tenfold excess of methylamine hydrochloride in a 30percent alcohol solution of methylamine at 150 deg C for 40 h leads to substitutioon of the methoxymethylamino group with a yield of 90percent.
