[reaction: see text] 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.

Organosilanols

Over the past several years, the Pd-catalyzed cross-coupling of silicon compounds (Hiyama coupling) has rapidly gained acceptance as a suitable alternative to more commonly used methods such as Stille (Sn), Kumada (Mg), Suzuki (B), and Negishi cross-couplings (Zn).
