A number of N-acyl-o-alkylhydroxylamines (2) have been prepared by alkylation of potassium salt of various hydroxamic acids (1) under different set of reaction con­ditions. Hydroxamic acids (3) obtained by acidic hydrolysis of potassium salt of hydroxamic acids were subjected to natation with various acylating agents to give o-acylhydroxamic acids (4). The structure assignments of 2 and 4 are based on elemental, ir and nmr spectral data.
