Title

HYDROXAMIC ACID : A CLASS OF CHEMICAL COMPOUNDS

Authors

Abstract

The structure of the hydroxamic acids was first brought to the attention of W. Lossen by the observation that the product obtained by the interaction of anisohydroxamic acid and benzoyl chloride was different from the product obtained with benzohydroxamic acid and anisoyl chloride. He introduced the term ‘metamers’ to describe these compounds erroneously believing that both acyl groups in each compound were attached to the nitrogen atom of the hydroxyl amine molecule. Later he realised that in the successive acylation of hydroxyl amine each of the hydrogens of the hydroxyl amine molecule behaved differently from the other two, and as a result of this, proposed the “hydroxy oxime” structure Rc(OH) =NOH. Such a structure served to explain the difference between ethyl benzohydroxamic acid C6H5C(OC2H5)=NOH and ethyl benzo hydroxamate C6H5-C(OH)=NOC2H5 , as well as the hydrolytic product obtained with a variety of acylated and alkylated mono-hydroxamic acids. He considered the α-, β- and γ-forms of dibenzoyl hydroxamate or the α- and β-forms of ethyl benzo hydroxamic acid in each instance as physically different manifestations of the same parent compound. It was at this time that he became considerably involved in a controversy on structure with Werner, Tiemann and others

Key Words

hydroxamic acids, acylated, dibenzoyl hydroxamate, ethyl benzo hydroxamic acid.
