Procedure

In a 500 ml four-neck round-bottom flask equipped with a stirrer, thermometer, standard taper glass stopper, stillhead with condenser, cooled distillate receiver and cold trap, 133 g of tributyltin ethyl phosphite and 68.7 g of lauryl alcohol are heated with stirring for about 5 hours at 140° C, a vacuum of about 30 - 5 mm Hg being applied for 1 hour. Ethanol is initially distilled off and then the excess lauryl alcohol is distilled. 178 g tributyltin lauryl phosphite are obtained.
