Preparation of 3-phenoxybenzyl 3(2,2-dihalovinyl)-2,2- dimethylcyclopropanecarboxylate

摘要

The insecticide, 3-phenoxybenzyl 3-(2,2-dihalovinyl)-2,2- dimethylcyclopropanecarboxylate, is produced in high yield by the alcoholysis of a lower alkyl 3-(2,2- dihalovinyl)-2,2- dimethylcyclopropanecarboxylate with 3-phenoxybenzyl alcohol in the presence of a catalytic quantity of lower alkyl titanium alkoxide.
