Abstract Silicachloride (SiO2-Cl), as a heterogeneous reagent, has been used for the efficient dehydration of tertiary alcohols under mild reaction conditions. For comparison, we have also used trimethylsilyl chloride (TMSCl) as a homogeneous reagent for this purpose. We have found that silicachloride is a more efficient reagnet than trimethylsilyl chloride for this purpose. Handling of SiO2-Cl is
