| | Potassium trimethylsilanolate Usage And Synthesis |
| 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. | | Purification Methods | Recrystallise it from H2O and dry it at 100o/1-2mm.
