Carbon tetrabromide → HCID 178447860, compound

Participants

Reaction Steps

26.9 g of carbon tetrabromide was dissolved in 82 ml of dichloromethane, and 42.6 g of triphenylphosphine was added at 0° C. or less. Next, 10 g of 4-(trans-4'-propylcyclohexyl)benzaldehyde was dissolved in 41 ml of dichloromethane, which then was added dropwise to the first dichloromethane solution over a period of one hour. The combined solutions were then agitated at room temperature for one hour. After completion of the reaction, the dichloromethane was distilled off, and 500 ml of hexane was added to the residue. The resulting crystals were filtrated and washed with hexane three times. The residue was subjected to recrystallization with hexane to obtain 16 g of 4-(trans-4'-propylcyclohexyl)-β,β-dibromostyrene.
