Toluene → HCID 22404526, compound

Participants

Reaction Steps

45.23 Grams of 2,3-dichloro-1-propene were added dropwise to a mixture of 20.00 g of methyl 2-methyl-1-propenyl ketone, 60 g of toluene, 60 g of water and 26.65 g of zinc powder at 35° C., and after the addition, the resultant mixture was maintained at the same temperature for 5 hours. After the reaction was completed, zinc-derived insolubles were filtered off, and the filtrate was separated. The organic phase was washed with 7% sodium carbonate aqueous solution and dried over magnesium sulfate. The desiccant was filtered off and the toluene was distilled off under reduced pressure. The resultant oily substance was purified by silica gel column chromatography to give 31.11 g of 2-chloro-4,6-dimethyl-1,5-heptadien-4-ol; nD25 =1.474, FI-MS m/e 174(M), 176(M+2).
