Triphenylphosphine → HCID 18504566, compound

Participants

Reaction Steps

To a solution of 0.44 g of 4-(3,3-dichloro-2-propenyloxy)-2,6-dichlorophenol, 0.20 g of 2-(2-hydroxyethyl)thiophene and 0.40 g of triphenylphosphine dissolved in 10 ml of tetrahydrofuran was added dropwise a solution of 0.31 g of diisopropyl azodicarboxylate dissolved in 5 ml of tetrahydrofuran, while stirring at room temperature. After stirring at room temperature for 12 hours, the reaction mixture was concentrated, to which 20 ml of diethyl ether was added, and the precipitate was filtered. The filtrate was concentrated, and the residue was subjected to silica gel chromatography, which afforded 0.38 g of 3,5-dichloro-4-(2-(2-thienyl)ethoxy)-1-(3,3-dichloro-2-propenyloxy)benzene (62% yield), nD25.6 1.5919.
