Luminescent rhenium fac-tricarbonyl-containing complexes of androgenic oxo-steroids†
Abstract
A new route to luminescent derivatives of androgenic steroids containing a ketone group in the 3- or 17-position has been developed. Reaction with the fac-Re(CO)3Cl complex of 3,3′-diamino-2,2′-bipyridine (complex 1) afforded a cyclic aminal product with different steroids. The rate of reaction and yield varies according to the conjugation or steric hindrance around the ketone group.
