REVIEWEDtruetrue3071false3071false0025-0155JournalHUNGARIAN97833934333951991The activity of montmorillonite-supported iron(III) nitrate and copper(II) nitrate was investigated in model oxidation and nitration reactions. It was established that, in contrast to literature data, even the less stable iron-reagent can be stored for weeks without substantial loss of activity. For complete oxidation of aromatic alcohols to carbonyl compounds there is no need for a significant excess of the reagents proposed in the literature. With an amount of iron-reagent less than the equivalent to the alcohol, the oxidation yield achieved was higher than proportional. This fact may place in doubt the adequacy of the accepted reaction mechanism. The rate of oxidation is markedly influenced by the nature of the solvent, the reaction is the fastest in benzene. The copper-reagent, which has not been used for this purpose before, is a good oxidant too. However, the oxidation yield with this reagent reaches that obtained with the iron reagent at a temperature by about 30-degrees-C higher. In the nitration of phenols the temperature could be increased to 60-degrees-C with the iron-reagent, so we have succeeded in reducing the reaction time to some hours.2009bme-pa-migracio-20014-06-20-v01falsefalsetruefalsetruefalseNONE2024-02-17false50513435555111405151011Afalsefalsefalsefalse2010-04-21T09:42:09.000+00002014-06-23T17:04:30.000+0000Budapesti Műszaki Egyetem16120trueLanguage10001
