is described, and the postcoital and uterotropic activities of these 1-trifluoromethyl-1,2,2-triphenylethylenes are determined. The parent compound and 3 substituted analogs were prepared by the stepwise replacement of the vinylic F atoms of hexafluoropropene with aryl groups from ArLi reagents. The postcoital antifertility and uterotrophic activities in the rat were determined by treating rats with

β,β-Diphenyl-α-(trifluoromethyl)vinylstannane 6 was prepared in good yield via several steps from 2,3,3,3-tetrafluoro-1-phenyl-1-phenylthiopropene. The cross-coupling reactions of 6 with aryl iodides in the presence of a catalytic amount of Pd(PPh3)4 and CuI provided trifluoromethylated triphenylethene derivatives 7 in high yields.
