Organosilanols

Pd-catalyzed cross-coupling of silicon compounds offers an alternative in synthetic chemistry.

Palladium-catalyzed silylation of aryl bromides leading to functionalized aryldimethylsilanols.

Scott E Denmark et al.

Organic letters, 5(19), 3483-3486 (2003-09-12)

[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.
