Process for the preparation of 16-methylene steroids, characterized in that 16-methylene-17-alpha-hydroxyprogesterone (I) is transformed by treatment with an 11-hydroxylating agent in 16-methylene-11,17-alpha- hydroxyprogesterone (III) and because this compound (III) is transformed for the preparation of the relevant 9-alpha-fluocompound by the action of a dehydroprogesterone medium (V), and because this compound (V) is treated after acylation of the group 17-alpha-hydroxyl successively with hypohologenous acid, with a means of dissociating hydrogen halide and fluorohydric acid, and because it is transformed by saponification in any reaction phase in known manner the 17-acyloxy group and/or because it is optionally introduced into the double-1,2 bond and/or because an 11-hydroxyl group is transformed into a 11-keto group.
