Synthesis of 2-(Diarylmethylene)-3-benzofuranones Promoted via Palladium-Catalyzed Reactions of Aryl iodides with 3-Aryl-1-(2-tert- butyldimethylsilyloxy)phenyl-2-propyn-1-ones

3-Substituted-1-(2-tert-butyldimethylsilyloxy)phenyl-2-propyn-1-ones were coupled with aryl iodides by using palladium as a catalyst in ambient MeOH solution and gave 2-(diarylmethylene)-3-benzofuranones in moderate to good yields.
