, p. 661 - 662 (1981)
Anodic chlorination of methoxy- and ethoxybenzenes yielded p-alkoxychlorobenzenes preferentially.The p-/o- ratios were 34.5 in N,N-dimethylacetamide-LiCl and 17.1 in N,N-dimethylformamide-LiCl.In the former case, the current efficiency for producing p-chloromethoxybenzene was 95.8percent at Pt anode.

, (2008/06/13)
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): STR1 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): STR2 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): STR3 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): STR4 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): STR5 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° to 50° C.
