클로로트리벤질실란 화학적 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).
