| Hazard Information | Back Directory | [Chemical Properties]
Potassium trimethylsilanolate is a white solid with slight odor, decomposes above 134 °C.
| [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. | [Production Methods]
109 kg of hexamethyldichlorosilane was put into a stirring kettle, and nitrogen was introduced at a flow rate of 1 L/min for 0.5 h while stirring. 56 kg of potassium hydroxide was added while stirring. After returning water at 100° C. for 10 h, the material was discharged into a centrifugal spray drying oven and centrifuged and spray-dried at 3000 rpm and 100° C. for 5 h to obtain white crystalline potassium trimethylsilanol with a purity of 99.99%.
| [Solubility in organics]
Potassium trimethylsilanolate is solubility in tetrahydrofuran, diethyl ether, toluene, dichloromethane, alcohols, and most other organic solvents. | [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.] | [References]
