Abstract: Transition metal acetylacetonates promoted aerobic oxidation methodology involving molecular oxygen as an oxidant with co-oxidant like isobutyraldehyde have been used for oxidative transformation of variety of tertiary nitrogen compounds to its N-oxides. The system of O2-aldehyde metal acetylacetonates needs shorter reaction time than simple molecular O2-aldehyde system without catalyst for oxidative conversion of tertiary nitrogen to corresponding N-oxides. The corresponding N-oxides have been obtained in near quantitative yield using transition metal acetylacetonates of Fe (II), Ni (II), VO (V) and Mn (II).
