Amides are an important class of organic compounds, which have widespread industrial applications. Transamidation of amides is a convenient method to generate new amides from existing ones. Tertiary amides, however, are challenging substrates for transamidation. Here we describe an unconventional approach to the transamidation of tertiary amides using nitroarenes as the nitrogen source under reductive conditions. Manganese metal alone mediates the reactions and no additional catalyst is required. The method exhibits broad scope and high functional group tolerance.

We demonstrate here, a new polystyrene supported Cu(ii) catalyzed proficient synthetic methodology for the facile N-arylation of aromatic, aliphatic, cyclic and heterocyclic amides with aryl halides under neat conditions. The catalyst, PS-Cu(ii)-ala, was prepared through the grafting of copper metal on a polystyrene-β-alanine imine network. The catalyst shows a wide range of substrate scope and excellent functional group tolerance, and produces the desired anilides in mostly high yields. The material is thoroughly characterized by DRS-UV, FT-IR, AAS, FE-SEM, TGA analysis and energy dispersive X-ray (EDX) studies. The catalyst can be easily recovered from the reaction medium and reused without significant loss of its catalytic activity suggesting future potential of this catalyst.

Di(hetero)arylamides have been synthesized in short reaction times by palladium-catalysed multicomponent aminocarbonylation of either electron-deficient or electron-rich heteroaryl halides and p-iodoanisole with, several, arylamines bearing either electro

(Chemical Equation Presented) A general nonoxidative N-amidation of organostannanes and boronic acids has been developed. Under nonbasic conditions a wide variety of aryl, alkenyl, and heteroaryl organostannanes and boronic acids couple efficiently with O-acetyl hydroxamic acids in the presence of Cu(I) sources.

A series of m- and p-substituted anilides of benzoic acid, 2-thienoic acid, and 2-furoic acid were prepared and their 1H and 13C nmr spectroscopic characteristics were examined. In general, good correlations were observed between the chemical shifts of proton and carbon signals of the acyl aromatic rings and the Hammett σ. Plots of the chemical shift values of the carbonyl carbons of the benzanilides against those of the 2-thienamides and 2-furamides gave an excellent correlation and the values of the slopes are 0.79 and 0.52, respectively, in dimethyl sulfoxide-d6. The slopes could be considered as a set of aromaticity index.
