A persulfate-promoted metal-free route in water toward the synthesis of unprecedented polyfunctionalized benzenes is reported. In our approach, the targeted products are delivered in high to moderate yields from phenylacetylenes and α,β-unsaturated compounds via the benzannulation reaction. This method has a good scope and gives access to functionalized benzene rings that offer a wealth of opportunities

Palladium-catalyzed Suzukicross-coupling of isomeric dichloroacetophenones with phenylboronic acid in the presence of 2-dicyclohexylphosphino-2′-(dimethylamino)-biphenyl (DavePHOS, a Buchwald ligand) affords the corresponding diphenylacetophenones in high yields. The reaction of pentachloroacetophenone with phenylboronic acid (1.1–2.5 equiv.) proceeds unselectively to give isomeric mono- and disubstitution
