N-bromobutanimide → HCID 56949709, compound

Participants

Reaction Steps

Crude isopropenyldiisopropylsilane (10 g), which was prepared as described in “Preparation of Isopropenyldiisopropylsilane—Method 2” was taken up in dichloromethane (120 mL) and cooled in an ice bath. N-Bromosuccinimide (13.7 g, 77 mmol, 1.2 eq. assuming silane purity of 100%) was added scoopwise over 1 hour, followed by an additional hour of stirring while maintaining the temperature. The suspension was filtered and the solid rinsed with pentane (50 mL). Solvent was removed by rotary evaporation and the suspension again taken up in pentane (70 mL), and filtered through quantitative filter paper, that was then rinsed with additional pentane (50 mL). Removal of solvent by rotary evaporation yielded crude isopropenyldiisopropylbromosilane (15 g) as a hazy, pale brown liquid.
