The controlled basic hydrolysis of tetrabutyl-1,3-dichlorodistannoxane under interfacial conditions was found to lead to α,ω-dichlorooligostannoxanes, Cl(SnBu2O)nSnBu2Cl, n being controlled by the molar ratio of base to distannoxane. These oligostannoxanes were identical with those prepared by other methods. They were used in the preparation of oligostannoxane dicarboxylates and organotin polyesters, having stannoxane recurring units in their backbone, by reaction with the sodium salts of mono- or dicarboxylic acids under interfacial conditions.

Hydrolysis Of

The rates of reaction of halide ions with ethylene oxide in neutral aqueous solution and the rate of hydrolysis of ethylene oxide in acid solution have been measured and the activation energies determined. From these data and from the ratio of glycol to chlorohydrin formed when ethylene oxide reacts with excess aqueous hydrogen halide, the rates of the acid-catalyzed addition of halide ions to ethylene oxide at 25 °C. have been estimated.
