클로로트리벤질실란 C화학적 특성, 용도, 생산
물리적 성질
mp 141–142 °C;1,2 a somewhat higher value (143–145 °C) is cited in the Aldrich catalog.용도
Tribenzylchlorosilane is widely used as reagent for alcohol protection.제조 방법
It is prepared by reaction of benzylmagnesium chloride with SiCl4 in ether; separation from mono- and dibenzylated chlorosilane byproducts is then accomplished by fractional distillation (boiling range 300–360 °C/100 mmHg). Other preparations involve the chlorination of tribenzylsilane using Cl2 or an acyl chloride. No yields are reported for any of the above preparative procedures.Purification Methods
It is recrystallised three times from pet ether (in slender colourless needles, m 141o). It is sparingly soluble in pet ether but is soluble in Et2O. It does not fume in moist air but is decomposed by H2O to give tribenzyl silanol m 106o (from pet ether).
