Etofenprox → 3-Phenoxytoluene

Participants

Reaction Steps

The dechlorination reaction was carried out in the same manner as in Example 1 except that 1.44 g of 10%-palladium-alumina (100% dry) was used instead of the 5%-palladium-carbon used as the hydrogenation catalyst in Example 1, and an oily product was obtained by carrying out the post-treatment in the same manner as in Example 1. From the results of the analysis of the oily product by gas chromatography according to the internal standard method, it was found that the oily product comprised 97.4% of 3-phenoxybenzyl 2-(4-ethoxyphenyl)-2-methylpropyl ether and 0.5% of unreacted starting 3-phenoxybenzyl 2-(3-chloro-4-ethoxyphenyl)-2-methylpropyl ether, and that the content of each of 3-phenoxytoluene and 4-ethoxyneophyl alcohol formed by cleaving of the ether linkage was lower than 0.7%. The amount of the obtained oily product was 52.0 g and the yield was 93.2%.
