A cheap, mild and environmentally friendly oxidation of tertiary amines and azines to the corresponding Noxides is reported by using polyfluoroalkyl ketones as efficient organocatalysts. 2,2,2-Trifluoroacetophenone was identified as the optimum catalyst for the oxidation of aliphatic tertiary amines and azines. This oxidation is chemoselective and proceeds in high-to-quantitative yields utilizing 10 mol% of the catalyst and H2O2 as the oxidant.
Use of amine oxide in the H2 O2 oxidation of aliphatic mercaptan to sulfonic acid

Hydrocarbyl mercaptans are oxidized to sulfonic acids by reaction with aqueous hydrogen peroxide in the presence of an inorganic base (e.g. sodium hydroxide) and a tert-amine oxide. The product is in the form of a sulfonate salt. The reaction rate is increased and undesirable free-oil by-product is decreased by the inclusion of the amine oxide catalyst.

EDA-iodine complex with trialkylamine oxides in dichloromethane have been investigated spectrophotometrically.Thermodynamic (KADc,-ΔG0) and spectral (ΕADλ) characteristics of these complexes were determined.The absorption band of iodine in the visible region was blue-shifted with a variable maximum, depending on the structure of the amine oxide.The KADc and ΕADλ values were calculated using a modified method.A non-linear relationship KADc=(R), where R is the number of carbon atoms in the alkyl chain, was found.
