Method for the preparation of difluoromethoxyaromatic compounds |
| abstract |
A method for the preparation of certain difluoromethoxyaromatic compounds which are useful intermediates for the preparation of pyrethroid pesticides. The method comprises alkylating a p-substituted phenol with excess chlorodifluoromethane at atmospheric and superatomspheric pressures in the presence of a base, acetone, benzyltriethylammonium chloride, and water. |
