実験手順

Imidazole (7.8 g, 115 mmol) was added to a solution of 3-iodophenol (12.7 g, 58 mmol) and tert-butyl(chloro)dimethylsilane (9.9 g, 65 mmol) in dichloromethane (80 mL) at 0° C. The reaction mixture was stirred at rt overnight. The suspension was washed three times with water and once with brine, dried and concentrated to give crude tert-butyl(3-iodophenoxy)dimethylsilane (20 g, 93%).
