3.9 g of sodium borohydride (0.1 mol) and 70 ml of monoglyme were mixed together in a 200 ml eggplant type flask and cooled to -10° C. 70 ml of a diglyme solution containing 10.0 g of triphenyltin chloride (0.026 mol) was added to this mixture dropwise for 30 minutes. Subsequently, the mixture was stirred for another 30 minutes at -10° C. Then diglyme was removed under a reduced pressure of greater than 1 mmHg at below 0° C. Then, the resultant residue was extracted with diethylether followed by concentration under reduced pressure to yield 9.1 g of the final product of triphenyltin hydride (yield=100%).
