Ohmicheating offers a very efficient way to perform organic reactions in aqueous media. Potentially bioactive (E)-3-styrylquinolin-4(1H)-ones were synthesized by the Heck reaction of 3-iodo-1-methylquinolin-4(1H)-one with styrenes in water and with ohmicheating. Pd(OAc)2 was used as catalyst, and tetrabutylammonium bromide was used as phase-transfer catalyst in the presence of an inorganic base.
