Trialkoxysilanes

The use of silicon compounds as transmetalation reagents has attracted much attention as a viable alternative to the popular Stille and Suzuki coupling reactions, mainly due to the formation of nontoxic byproducts and the stability of the reagents to many reaction conditions. Silicon-based coupling reactions can be carried out using aryl, heteroaryl, or alkenyl halides and alkoxysilanes in the presence of palladium or rhodium catalysts.

Among the various types of silicon compounds available, alkoxysilanes are the most effective in the coupling reactions.

Trialkoxysilanes are important silylating agents, and are widely used for surface functionalization via modification of substrates under standard solution deposition conditions. As a practical alternative to Stille and Suzuki coupling, the rhodium-catalyzed addition of trialkoxysilanes to carbonyl compounds has received a considerable amount of attention. Sigma-Aldrich is proud to contribute to this field by making a broad variety of trialkoxysilanes available to our customers.
