STABLE FREE NITROXYL RADICALS AS OXIDATION CATALYSTS AND PROCESS FOR OXIDATION |
摘要 |
<p>The instant invention relates to stable free nitroxyl radicals of formula (I) wherein at least one of the substituents R is -O. and the others are hydrogen or OH; X is -NR<SUB>1</SUB>R<SUB>2</SUB>, wherein R<SUB>1 </SUB>and R<SUB>2 </SUB>are independently hydrogen, C<SUB>1</SUB>-C<SUB>18</SUB>alkyl or together with the nitrogen atom to which they are bound form a 5 or 6 membered ring which may be further interrupted by an O atom. Further subjects of the invention are an oxidation process for alcohols to aldehydes or ketones or to carboxylic acids in the presence of a compound of formula (I) and the use of stable free nitroxyl radicals of formula (I) as oxidation catalysts.</p> |
