ACYL CHLORIDES OF 2,2,5,5-TETRAMETHYL-3-IMIDAZOLIN-1-OXYL-4-O-ACYLHYDROXIMIC ACIDS

Article abstract of DOI:10.1007/BF00965436

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 derivatives that reaction of the obtained acyl chlorides with nucleophilic reagents usually gives products of chlorine atom substitution with simultaneous cleavage of the acyl group.
