Acyl chlorides of 2,2,5,5-tetramethyl-3-imidazolin-1-oxyl-4-0-acylhydroximic acids
摘要:
Acylation of nitroenamine derivatives of imidazolidin-1-oxyl with carboxylic acid chlorides leads to O-acylhydroximic acid chloride derivatives of 3-imidazolin-1-oxyl. The reaction proceeds apparently through a nitrile oxide. It was shown for the O-benzoyl derivative that reaction of the obtained acyl chlorides with nucleophilic reagents usually gives products of chlorine atom substitution with simultaneous cleavage of the acyl group.
