Luminescent rhenium fac-tricarbonyl-containing complexes of androgenic oxo-steroids.

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)(3)Cl 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.

fac−Re(I)(tricarbonyl) complexes with anionic bidentate ligands

Investigation of the photophysical and photochemical properties of d transition metals, e.g. Ru(II), Re(I) or Os(II), complexes with heteroaromatic diimine ligands (N∩N) is one of the main topics of modern inorganic physical chemistry. In general, the excited state behaviour of such compounds is governed by the interplay between the metal-to-ligand (MLCT) charge-transfer and intra-ligand excite...

synthesis of binuclear platinum complexes containing biphosphine ligand

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
