We herein describe the labelling of ethynylestradiol with metal carbonyl fragments, namely -Co2(CO)6, -M3(mu-CO)(CO)9 (M = Ru, Os) and -Ru3(mu-H)(CO)9. The solution structure of RU3(mu-CO)(CO)9 (ethynylestradiol) cluster has been studied by means of variable-temperature (VT) C-13 NMR spectroscopy. This derivatization can be useful for detection enhancement in high-performance liquid chromatography (HPLC) separation, since the metal carbonyl moieties act as efficient markers for the UV detection mode at the usually employed 254 nm wavelength.

Abstract
We herein describe the labelling of ethynylestradiol with metal carbonyl fragments, namely -Co2(CO)6, -M3(mu-CO)(CO)9 (M = Ru, Os) and -Ru3(mu-H)(CO)9. The solution structure of RU3(mu-CO)(CO)9 (ethynylestradiol) cluster has been studied by means of variable-temperature (VT) C-13 NMR spectroscopy. This derivatization can be useful for detection enhancement in high-performance liquid chromatography (HPLC) separation, since the metal carbonyl moieties act as efficient markers for the UV detection mode at the usually employed 254 nm wavelength.
