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

Participants

Reaction Steps

To a solution of 0.33 g of 2-(3-hydroxypropyloxy)-5-trifluoromethylpyridine, 0.40 g of 2-chloro-6-methyl-4-(3,3-dichloro-2-propenyloxy)phenol and 0.41 g of triphenylphosphine dissolved in 30 ml of dichloromethane was added dropwise a solution of 0.32 g of diisopropyl azodicarboxylate dissolved in 3 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 0.56 g of 3-chloro-5-methyl-4-[3-(5-trifluoromethyl-2-pyridyloxy)propyloxy]-1-(3,3-dichloro-2-propenyloxy)benzene (92% yield), nD23.6 1.5294.
