                                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.
