In a 500 mL three-necked flask, trimethylsilyl chloride (170 g, 109 mmol) was added to tricyclohexyltin hydroxide (80 g, 133 mmol) and heated at reflux during 18 hours. After distillation of trimethylsilyl chloride in excess and hexamethyldisiloxane under reduced pressure, the crude product was recrystallized in petroleum ether. White needles were obtained (39.82 g, 79.6 mmol).
