In addition, there is a lot of other information about this compound (cas:1273-73-0) here.

The X-ray structure of 17α-ferrocenylestradiol shows that the ferrocenyl group is at the α-position of the steroid, below the plane of the D ring. From acidic medium it is possible to obtain and isolate the derivative with a carbenium ion in 17-α position. This ion is transformed by various nucleophiles into the C(16)-C(17)-unsaturated derivative With NaBH4 in acidic medium the reduction leads to a mixture of 17α- and 17β-ferrocenylestrol with a predominance of the β product, owing to a more favorable entrance of hydride in the α position. The oxidized derivative 17α-ferrociniumylestradiol tetrafluoroborate was prepared and its properties are described.
