Oxidative Cyclization of Diamides by Phenyliodoso Acetate

Carboxamides containing a suitably situated nucleophilic group (carboxamide, N-substituted carboxamide, or hydroxymethyl) undergo oxidation by phenyliodoso acetate to afford heterocyclic products through internal attack on the initially formed isocyanate.N-Substituted carboxamido groups are the least effective of these internal traps.Phenyliodoso acetate is much superior to lead(IV) acetate for oxidative cyclization of maleamide and various substituted propanediamides, but is not suitable for butanediamide.

A study of the nature and distribution of radicals produced by the radiolysis of amides in the solid state has been made by two complemetary methods: (i) final product analysis by capillary gas chromatography and (ii) the direct observation of radicals by electron spin resonance spectroscopy.The dimer isomer distribution for N-methylformamide (NMF), N-methylacetamide (NMA) and N,N-dimethylformamide (DMF) allows one to estimate the parent radical distribution by using a statistical rule for dimer formation.In the solid state the radiolytic formation of radicals is selective.Final product analysis by capillary gas chromatography and the direct study of radicals by pulse radiolysis are also complemetary methods for studying the nature of radicals produced from the radiolysis of amides in aqueous solutions.The selective production of one parent radical is characteristic of dilute solutions.

Alkyl amides have been synthesized from cyclic anhydrides, carboxyl acids and their esters by contacting them with an amine carbamic acid salt.
