Procedure

A mixture of di-n-butyltin oxide (2.14 g, 8.6 mmol) and di-n-butyltin diisothiocyanate (1.0 g, 2.8 mmol) in ethanol (30 mL) was heated to reflux for 6 hours during which time the white slurry became a clear solution. The reaction mixture was concentrated via rotary evaporator to a solid which was pulverized and left exposed at ambient temperature for 18 hours. The powder was recrystallized from hexanes at 0° C. to give the title compound as a white solid (2.74 g, 86%).
