Triphenylphosphine → HCID 18429639, compound

Participants

Reaction Steps

To a mixture of 3.40 g of p-(hydroxymethyl)benzaldehyde obtained in the same manner as described above, 7.2 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 6.56 g of triphenylphosphine, and 50 ml of tetrahydrofuran was slowly added dropwise 5.05 g of diisopropyl azodicarboxylate with stirring under ice cooling. After stirring at room temperature for 12 hours, the reaction mixture was concentrated to give a residue. This residue was subjected to silica gel chromatography, which afforded 4.75 g (yield, 46%) of 4-((2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)methyl)benzaldehyde, m.p., 93.9° C.
