Procedure

In a 500 ml four-neck round-bottom flask having a thermometer, stirrer, standard taper glass stopper, stillhead with condenser, cooled distillate receiver and cold trap, 116.4 g of tributyltin acetate and 92 g of diethyl phosphite are heated with stirring to about 150° with ethyl acetate being distilled off. After a reaction time of 6 hours, of which one hour is under vacuum, ca. 5 mm Hg, the excess dimethyl phosphite is distilled off and 134 g of tributyltin ethyl phosphite are obtained.
