Description and Uses

Potassium trimethylsilanolate can be used as a reagent in the:

• Hydrolysis of nitriles to primary amides.
• Conversion of esters to carboxylic acids, and dialkyl phosphonates to their monoalkyl phosphonates.
• Synthesis of E-alkenes, and nitrocefin.

It can also be used as a coupling promoter in cross-coupling reaction of aliphatic alkynylsilanols with aryl iodides.
