o-hydroxybenzaldehyde oxime, o-hydroxyacetophenone oxime, o-hydroxybenzophenone oxime, and their 5-Cl and 5-NO2 derivatives were prepared by several methods. For aminolysis with benzylamine, esters 1 show higher reactivity than similar esters containing no hydroxyl group in the ortho position. It is suggested that esters 1 forms an intramolecular hydrogen bond between the hydrogen of the hydroxyl group at the ortho
