专利汇可以提供Production of 3-phenoxybenzyl 2-(4-alkoxyphenyl)-2-methylpropyl ether专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain the titled compound safely and economically in high yield without requiring a hydrogen gas, by carrying out a reduction reaction of dehalogenation by hydrogenation of a specific compound in the presence of a hydrogenation catalyst by the use of an alcohol and an alkali compound as a hydrogenating and reducing agent.
CONSTITUTION: A 3-phenoxybenzyl 2-(4-alkoxy-3-halogenophenyl)-2-methylpropyl ether or 3-phenoxybenzyl 2-(4-alkoxy-3,5-dihalogenophenyl)-2-methylpropyl ether shown by the formula I (R is lower alkyl; X
1 and X
2 are H or F; Y
1 and Y
2 are H, Cl, Br, or I and at least one of Y
1 and Y
2 is Cl, Br or I) is dechlorinated, debrominated or deiodated in the presence of a hydrogenation catalyst such as Pd-C, etc. by the use of a lower fatty alcohol such as methanol, etc. and an alkali compound of an alkaline (earth) metallic hydroxide such as NaOH, etc. to give the aimed compound shown by the formula II useful as a controlling agent for insect pests.
