What is Potassium trimethylsilanolate?

The Uses of Potassium trimethylsilanolate

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.

Purification Methods

Recrystallise it from H2O and dry it at 100o/1-2mm. [Hyde et al. J Am Chem Soc 75 5615 1953, IR: Tatlock & Rochow J Org Chem 17 1555 1952, Beilstein 4 IV 3992.]
