The reaction of N-benzoyl-N-t-butylhydroxylamine with thionylchloride in carbon tetrachloride gave O-chlorosulfinylbenzohydroximoyl chloride as the main product. On treating with ethanol, the compound gave benzohydroximoyl chloride in good yield. The reaction was applied to the synthesis of substituted benzohydroximoyl chlorides.

constants for the hydrogen exchange reactions between N-t-butylhydroxamicacids and the stable piperidine N-oxyl (1); since the O–H bond strength in (1)-H is known, this gives an estimate of the O–H bond strengths in the hydroxamic acids. These are found to be stronger than those in dialkyl nitroxide and increase with increasing electron demand in the acyl group.
