Triphenylphosphine → 3-Chloro-5-methyl-4-[4-(5-trifluoromethyl-2-pyridyloxy)butyloxy]-1-(3,3-dichloro-2-propenyloxy)benzene

Participants

Reaction Steps

To a solution of 0.26 g of 2-(4-hydroxybutyloxy)-5-trifluoromethylpyridine, 0.3 g of 2-chloro-6-methyl-4-(3,3-dichloro-2-propenyloxy)phenol and 0.31 g of triphenylphosphine dissolved in 30 ml of dichloromethane was added dropwise a solution of 0.24 g of diisopropyl azodicarboxylate dissolved in 5 ml of dichloromethane, while stirring at room temperature. After stirring at room temperature for 24 hours, the reaction mixture was concentrated to obtain a residue. The residue was subjected to silica gel chromatography, which afforded 0.50 g of 3-chloro-5-methyl-4-[4-(5-trifluoromethyl-2-pyridyloxy)butyloxy]-1-(3,3-dichloro-2-propenyloxy)benzene (89% yield), nD23.0 1.5275.
