N-fluoro-N-perfluoromethyl sulfonamide compounds are provided as fluorinating agents for the fluorination of organic compounds by either the direct electrophilic fluorination of organic compounds or by the fluorination of organic compound carbanions.

′ have the meanings that are indicated in the description, as pharmaceutical active ingredients that have in vitro a higher affinity to estrogen receptor preparations of rat prostates than to estrogen receptor preparations of rat uteri and in vivo a preferential action on bone in comparison to the uterus, and/or pronounced action relative to the stimulation of the expression of 5HT2a-receptors and transporters, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds.
The invention further describes the use of steroids, on which the gonatriene skeleton is based, for treatment of estrogen-deficiency-induced diseases and conditions as well as the use of the gonatriene structural part in the total structures of compounds that have a dissociation in favor of their estrogenic action on bone in comparison to the uterus.

2-Fluoro-17β-estradiol is synthesized by mercurating at C-2 a 17β-estradiol diester or dietherate, displacing the mercury group with fluorine and then removing the ester- or ether-protecting groups.
