Procedure

20.8 g (0.16 mol) of the methyldiisopropylsilane prepared under Example 2, above, was placed in a 50 mL three-neck flask equipped with a reflux condenser, thermometer, and addition funnel. 25 g bromine (0.16 mol) was cautiously dripped in while cooling with ice and stirring with a magnetic stirring bar. A strong exothermic reaction developed, and hydrogen bromide was evolved. After addition of the entire quantity of bromine, the reaction was allowed to stand for 1 hour at room temperature and was then distilled in vacuo. 26.3 g (0.13 mol) of the target methyldiisopropylbromosilane (bp=92 degrees Centigrade/50 mmHg) was obtained.
