4,4′-Difluorobenzhydryl chloride Use and Manufacturing

Methods of Manufacturing

Condensation with fluorobenzene and carbon tetrafluoride with the participation of anhydrous aluminum trichloride, and then hydrolyzes to produce 4, 4'-difluorobenzophenone, which is then reduced to 4, 4'-difluorobenzyl alcohol. The product is obtained by chlorination.

Uses

Used as pharmaceutical intermediate
