Process for oxidation of substrates containing methyl, methylene or methin groups

Oxidation of substrates containing methyl, methylene or methine groups with oxygen to the corresponding oxo compounds is carried out with a 2-20C aromatic or aliphatic aldehyde in an organic solvent in the presence of: (a) an N-(hydr)oxysuccinimide or -maleimide (IA) or N-(hydr)oxyglutarimide (IB) a...

More Information
Summary:Oxidation of substrates containing methyl, methylene or methine groups with oxygen to the corresponding oxo compounds is carried out with a 2-20C aromatic or aliphatic aldehyde in an organic solvent in the presence of: (a) an N-(hydr)oxysuccinimide or -maleimide (IA) or N-(hydr)oxyglutarimide (IB) and (b) a cocatalyst containing transition metal, group 2A and/or 3A element(s). Oxidation of substrates containing methyl (CH3), methylene (CH2) or methine (CH) groups with oxygen to the corresponding oxo compounds is carried out with a 2-20C aromatic or aliphatic aldehyde in an organic solvent in the presence of: (a) an N-(hydr)oxy-succinimide or -maleimide of formula (IA) or an N-(hydr)oxyglutarimide of formula (IB); and (b) a cocatalyst containing transition metal, group 2A and/or 3A element(s); R1, R2 = H, OH, halogen, 1-20C alk(en)yl or alkoxy, aryl, 1-6C acyl, carboxy or 1-10C alkoxycarbonyl; or R R = a double bond in (IA); or R1R2 = a group forming a (non)aromatic ring system; X = O or OH; n = 1-3.
