CuSO4-mediated decarboxylative C-N cross-coupling of aromatic carboxylic acid with amide has been developed, leading to N-arylamides in modest to excellent yields. Anilines bearing electron-withdrawing substituents could also couple efficiently

The photocyclization of N-acyl-2-nitridiphenylamines to phenazine N-oxides is extended to several dinitro derivatives and a pyridine analogue obtaining N-oxides of otherwise difficult access.In the presence of some additives, the reaction takes a different course.Thus, with acids deacylation occurs, with triphenylphosphine a N-phosphoranylidene amine is formed and with 2,6-di-tert-butylphenol the corresponding nitrosodiphenylammine is obtained.A mechanism starting from the nitroamide triplet and involving several discrete intermediates is proposed in order to account for such observations.
