The polystyrene supported palladium (Pd@PS) nanoparticles catalyzed decarboxylative coupling of arylhalides and alkynyl carboxylic acids was developed for the synthesis of diaryl alkynes, indoles and pyrrolines.
An efficient and facile protocol for the synthesis of 3-aryl-imidazo[1,2-a]pyridines was investigated via palladium-catalyzed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids.
