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.]
