CHLOROTRIBENZYLSILANE Chemical Properties,Usage,Production

  • Physical properties mp 141–142 °C;1,2 a somewhat higher value (143–145 °C) is cited in the Aldrich catalog.
  • Uses Tribenzylchlorosilane is widely used as reagent for alcohol protection.
  • Preparation 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).
