Palladium-Catalyzed Silylation of Aryl Bromides Leading to Functionalized Aryldimethylsilanols
摘要:
[GRAPHICS]A mild and general palladium-catalyzed insertion of 1,2-diethoxy-1,1,2,2-tetramethyldisilane into a variety of aryl bromides affords the aryldimethylsilyl ethers in high yields. Hydrolysis of the ethers under pH-optimized conditions results in the exclusive formation of the desired aryldimethylsilanols.
