Abstract
N-n-Butylanilines undergo N-dealkylation to give a primary amine and butyraldehyde by oxidation with oxygen in the presence of bis(salicylaldehyde)ethylenedi-iminecobalt(II)(CoIIsalen) as catalyst. High conversions are obtained with high catalyst concentrations and low [substrate]/[catalyst] ratios (r). Inspection of the effect of catalyst and substrate concentrations on initial reaction rates (vin) shows poor sensitivity to the electronic effect of the nuclear substituent. Some anilines give azo derivatives at a lower rate in the same conditions.Keywords
