| titleOfInvention | Process for preparing 3-phenoxybenzyl-2- (4-alkoxyphenyl) -2-methylpropyl ethers. |
| abstract | The present invention relates to a process for producing 3-phenoxybenzyl 2-(4-alkoxyphenyl)-2-methylpropyl ethers having excellent insecticidal and acaricidal activities which are represented by formula (IV): <IMAGE> (IV) wherein R is a lower alkyl group and X1 and X2 are each a hydrogen or fluorine atom, which comprises reacting a 3-halogeno-4-alkoxyneophyl halide represented by the formula (I): <IMAGE> (I) wherein Y1 and Y2 are each a hydrogen, chlorine or bromine atom, at least one of them being a chlorine or bromine atom, R has the same meaning as above and X is a halogen atom, with a 3-phenoxybenzyl alcohol represented by the formula (II): <IMAGE> (II) wherein X1 and X2 have the same meaning as above, in the presence of a base to obtain a 3-phenoxybenzyl 2-(4-alkoxy-3-halogenophenyl)-2-methylpropyl ether represented by the formula (III): <IMAGE> (III) wherein Y1, Y2, R, X1 and X2 have the same meaning as above, and then subjecting the product to a hydrodehalogenation reaction, and relates to a process for producing a 3-halogeno-4-alkoxyneophyl halide represented by formula (I), which comprises reacting a 2-halogeno-1-alkoxybenzene represented by formula (V): <IMAGE> (V) wherein Y1 and Y2 are each a hydrogen, chlorine or bromine atom, at least one of them being a chlorine or bromine atom, and R represents a lower alkyl group, with a methallyl halide in the presence of an acid catalyst at -20 DEG to 50 DEG C. |
