An efficient and practical decarboxylative cross-coupling reaction of quinolin-4(1H)-one 3-carboxylic acids with (hetero)arylhalides has been established. Under a bimetallic system of PdBr2 and silver carbonate, the protocol proved to be general, and a variety of 3-(hetero)aryl 4-quinolinones and related heterocycles, such as 3-aryl-1,8-naphthyridin-4(1H)-ones, 3-arylcoumarins, 3-arylquinolin-2(1H)-ones

5,7-dihydroxy-4-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(1), 5,7-dihydroxy-3-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(2) and their derivatives 3 - 6. It has been assigned a novel structure having the phenyl substituent in the benzenoid ring of the coumarin nucleus - 4,5-dihydroxy-7-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(11).
