Description

General description

Sodium trimethylsilanolate is a versatile and very powerful reagent for the conversion of esters to carboxylic acids and the hydrolysis of nitriles to primary amides. It can be used as a starting material for the synthesis of metal silanolates via the salt metathesis and as a catalyst for the silylation of silanols with hydrosilanes.

Application

Sodium trimethylsilanolate is used as a catalyst in the:

• Synthesis of the rhodium silonate complex.
• Silylation of methylphenylsilane with tert-butyldimethylsilanol to synthesize trisiloxanes.
