Participants

Reaction Steps

To a mixture of 0.30 g of 4-(3,3-dichloro-2-propenyloxy)butanol, 0.43 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 0.39 g of triphenylphosphine and 15 ml of tetrahydrofuran was slowly added dropwise 0.30 g of diisopropyl azodicarboxylate with stirring under ice cooling. After stirring at room temperature for 24 hours, the reaction mixture was concentrated. The residue was subjected to silica gel chromatography, which afforded 0.34 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(4-(3,3-dichloro-2-propenyloxy)butyloxy)benzene (yield, 73%), nD24.5 1.5519.
