Reaction Steps
4-Bromobutyltrimethylsilane was prepared by the procedure of Perklev, Chem. Abstr., 49, 1541 (1955), involving the preparation of the Grignard reagent from 4-bromo-1-butene, its reaction with trimethylchlorosilane to give 3-butenyltrimethylsilane, and free radical catalyzed HBr addition. The latter addition gave 90% primary bromide. Using inadequate initiator gave mainly secondary bromide.
