Abstract
Process for generating 1O2 in which a ferrocene of the formula Fc(X)n (I) in which Fc is a ferrocene optionally substituted by dimethylaminoethyl, C1-C12-alkyl, aryl or carboxyalkyl, n may be 1 or 2 and X is a radical of the formula —(C1-C2-alkyl)m-P(R1)2 (II) where m may be 0 or 1 and R1 is phenyl, cyclohexyl, tert-butyl, ethyl, isopropyl, methyl, methoxy, ethoxy, phenoxy or butoxy, is treated in an organic solvent at a temperature of from −80° C. to +20° C. with 1 to 4 mol of ozone per mole of ferrocene compound, during which 1O2 forms, and use thereof for the oxidation of organic substrates which react with 1O2.
Claims9
A process for generating 1O2, which comprises treating a ferrocene of the formula
- Fc(X)n (I)
- in which Fc is a ferrocene optionally substituted by dimethylaminoethyl, C1-C12-alkyl, aryl or carboxyalkyl, n may be 1 or 2 and X is a radical of the formula
- —(C1-C2-alkyl)m-P(R1)2 (II)
- where m may be 0 or 1 and R1 is phenyl, cyclohexyl, tert-butyl, ethyl, isopropyl, methyl, methoxy, ethoxy, phenoxy or butoxy, in an organic solvent at a temperature of from −80° C. to +20° C. with 1 to 4 mol of ozone per mole of ferrocene compound, as a result of which 1O2 forms.
