125.40 Grams of 2,3-dichloro-1-propene were added dropwise to a mixture of 60.00 g of benzaldehyde, 180 g of toluene, 240 g of 5% acetic acid and 73.88 g of zinc powder at 45° C., and then the mixture was allowed to react at the same temperature for 3 hours. After the reaction was completed zinc-derived insolubles were filtered off, and the resultant filtrate was subjected to separation. The organic phase was washed with a 7% sodium carbonate aqueous solution and dried over sodium sulfate. The desiccant was filtered off, and then the toluene was distilled off under reduced pressure to give 98.23 g of 2-chloroallylphenylcarbinol. The results were as follows.
