Beschreibung

General description

Asymmetric catalytic addition of ethyl groups to 3′-(trifluoromethyl)acetophenone catalyzed by ligands derived from trans-1,2-diaminocyclohexane and camphor sulfonyl chloride has been reported. Phenylation of 3′-(trifluoromethyl)acetophenone in the presence of dihydroxy bis(sulfonamide) ligand (enantioselective catalyst), titanium tetraisopropoxide and diphenylzinc has been investigated.

Application

3′-(Trifluoromethyl)acetophenone has been used in a key step during the preparation of a commercial fungicide.
