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

The electron impact mass spectra (EI/MS) of 2- and 3-carboxanilides are dominated by the peak due to the corresponding thenoyl cations formed by cleavage of the C-N amide bond.This reaction is not affected by the polar effect of the substituents present in the phenyl ring.Most of the 2'-substituted derivatives undergo a cyclisation reaction with ejection of the substituent.In addition, for 2'-methyl and 2'-ethyl derivatives of both series of thiophene anilides a cryptic "ortho"-effect was suggested as responsible of the charge retention in the aniline moiety.
