Anwendungen & Verwendung
Verwenden
Tribenzylchlorosilane is widely used as reagent for alcohol protection.
Herstellung & Synthese
synthetische
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.
