Carbon tetrabromide → 1-(2-Bromo-ethyl)-4-propylidenecyclohexane

Participants

Reaction Steps

40.4 g of 2-(4-propylidenecyclohexyl)ethanol, 69.5 g of triphenylphosphine and 500 ml of acetonitrile were cooled to -5° C. A solution of 99.5 g of tetrabromomethane in 100 ml of acetonitrile was then added with stirring, and the mixture was stirred at RT overnight. The solvent was then removed, and the residue was subjected to conventional work-up, giving 1-(2-bromo-ethyl)-4-propylidenecyclohexane.
