Abstract: A chitosan-derived metal-free N-doped carbon catalyst is synthesized and investigated for selective reductive formylation of quinoline to N-formyl-tetrahydroquinoline and nitroarenes to N-formyl anilides via aqueous HCOOH (FA) mediated catalytic transformation. FA dissociates on the catalyst… read more here.
