Epimerizations of 16 alpha-chloro- (1a), bromo- (1b), and iodo-3 beta-hydroxy-5-androsten-17-one (1c) by a brief treatment with 0.2 equiv NaOH in aqueous pyridine reached equilibrium between 16 alpha- and 16 beta-halo ketones. 16 alpha-/16 beta-Halo ketone ratios at equilibrium were 1.5 for Cl, 1.25 for Br, and 1.0 for I. Kinetic analysis showed that(More)
