    摘要: 17.alpha.-bromo-.alpha. and 17.alpha.-iodo-vinyl-estrane derivatives of general formula I ##STR1## wherein X is a bromine or iodine atom in Z or E position,R.sup.1 is hydrogen, hydroxy or acyloxy with up to 3 C atoms,R.sup.2 is hydrogen, alkyl with up to 3 C atoms and alkanoyl and aroyl with up to 7 C atoms,R.sup.3 is hydrogen or methyl,R.sup.4 is a hydrogen atom in the .alpha. or .beta. position,R.sup.5 is hydrogen, methyl or methoxy andR.sup.6 is hydrogen or methyl,are pharmacologically effective with a profile of action like ethinylestradiol and in the form of their radioactively labeled compounds are also valuable diagnostic media.The Z-isomers can be prepared by a new process by reaction of the corresponding 17.alpha.-ethinyl steroids with trialkyl (or phenyl) tin hydride with addition of a free radical former.
