The title compound, C(21)H(19)ClF(3)NO, was synthesized from 3-[(E)-2-chloro-3,3,3-trifluoro-prop-1-en-yl]-2,2-dimethyl-cyclo-propane-carboxylic acid and diphenyl-amine. The propenyl and carboxamide substituents lie on the same side of the cyclo-propane ring plane, with the two methyl substituents on either side of the plane. The phenyl rings of the carboxamide are inclined at an angle of 84.6 ...
