and iodohexestrols and 2- and 4-substituted estradiols have bindingaffinities considerably lower than those of the fluoro compounds, the 4-substituted estradiols have affinities greater than the corresponding 2-substituted isomers. Introduction of a halogen (Cl, Br, I) at the 16 alpha position of 17 beta-estradiol results in compounds with receptor affinities comparable to that of 17 beta-estradiol itself;
