Potassium trimethylsilanolate Chemical Properties,Usage,Production

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.]
