Summary
In the reaction of tetrahydropyran with chlorosilanes in presence of anhydrous zinc chloride the ring is opened with formation of 1,5-dichloropentane and chlorine-substituted orthosilicic esters. The relative amounts of these products depend on the number of chlorine atoms in the molecule of the chlorosilane with which the tetrahydropyran reacts.
