Synthesis of functionalized triarylmethanes and pyranones based on cyclization reactions of free and masked dianions and regioselective palladium(0) catalyzed reactions of functionalized sulfones benzophenones pyrazoles indenones and furans Functionalized triarylmethanes were prepared with [3+3] cyclization. 2 3 dihydro fluorinated and non fluorinated pyranones were prepared in one step strategy. The Regioselective Suzuki Miyaura and Sonogashira reaction of the bis(triflates) of 2 4 dihydroxybenzophenone and 2 4 dihydroxydiphenylsulfone and 2 3 Dibromoindenone with arylboronic acids gave 2 4 diarylbenzophenones and 2 3 dibromoindenone were also studied. Furthermore The Suzuki Miyaura reactions of N protected 3 4 5 tribromopyrazole 2 3 4 5 tetrabromofuran.
