Method for the preparation of difluoromethoxyaromatic compounds |
| abstract |
A method for the preparation of certain difluoromethoxyaromatic compounds useful as intermediates in the preparation of pyrethroid pesticides. The method comprises alkylating a p-substituted phenol with excess chlorodifluoromethane at atmospheric or superatmospheric pressures in the presence of a base, water, and an inert water miscible organic solvent or solvent mixtures. |
