o-Nitroaniline derivatives. Part I. The preparation and stability of o-nitroanils
Abstract
The formation of Schiff bases by treatment of benzaldehyde with o-nitroaniline and its derivatives proceeds best in the presence of an excess of aldehyde, under conditions which permit removal of water as soon as it is formed. The products obtained from the corresponding reactions with substituted benzaldehydes depend on the nature of the substituents.
