Reactions of Stannic alkoxides with Glycols

A number of di-isopropoxy mono-glycollate and diglycollate derivatives of tin have been described for the first time by the reaction between stannic isopropoxide and various glycols in 1:1 and 1:2 molar ratios. A few mixed ethylene glycollates have also been isolated. With a view to synthesizing some volatile deriva­tives the reactions of monomeric stannic tertiary butoxide with some of these branched glycols were also investigated. The determination of molecular weights showed them to be polymeric.
