Reaction Steps
2.0005 g (5.54 mol) of dioctyltin oxide and 0.344 g (5.54 mmol) of ethylene glycol were introduced into a 100 ml reaction vessel equipped with a Dean-Stark device, and the atmosphere in the reaction vessel was replaced by argon. 70 ml of toluene was added, and the mixture was dehydrated by azeotropic distillation at 135° C. and stirred for 25.5 hours during which it became an uniform solution. After left and cooled to 60° C., the toluene was distilled off under reduced pressure. The resulting white solids were dried at 60° C. for 5 hours in vaccuo to give 1,1-dioctylstanna-2,5-dioxacyclopentane, 2.19 g (97.6% yield).
