This invention describes the new 11&bgr;-halogen-7&agr;-substituted estratrienes of general formula I
1
in which
R
11
is a fluorine or chlorine atom, and the other substituents have the meanings that are explained in more detail in the description.
The compounds have antiestrogenic properties or tissue-selective estrogenic properties and are suitable for the production of pharmaceutical agents.

11α-Hydroxy-19-nor-steroids react with N-(2-chloro-1,1,2-trifluoroethyl)diethylamine to give the 11β-fluoro-derivatives or, in presence of lithium chloride or lithium bromide, the 11β-chloro- and 11β-bromo-derivatives, respectively.
The invention relates to 11β-halogen steroids with general formula (I), whereby R
11
is halogen, X—Y-Z represents a group with one of the two structures CH═C—C or CH
2
—C═C and the other radicals have the meaning that is indicated in the claims, also the production and use of these compounds for the production of pharmaceutical agents as well as pharmaceutical preparations that contain 11β-halogen steroids.
