Avoid Falsely Accusing Female Athletes Who Use Levonorgestrel of Doping

Drug Testing and Analysis, EarlyView.
Levonorgestrel, a hormonal contraceptive, metabolises to 18‐methyl‐19‐noretiocholanolone which is also the main metabolite of the prohibited substance 18‐methyl‐19‐nortestosterone. Analysing for levonorgestrel and/or tetrahydronorgestrel is essential to avoid misinterpreting 18‐methyl‐19‐noretiocholanolone findings.

Following the In Situ Pathway of Photoactivated Cyclopentadienone–NHC Iron Complexes as Ammonia–Borane Dehydrocoupling Bifunctional Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Iron complexes bearing cyclopentadienone/hydroxycyclopentadienyl and NHC ligands in combination with carbonyls are active in ammonia–borane dehydrogenation. In situ IR and scale up experiments give insight in the catalytic mechanism. Carbonyl iron complexes, bearing cyclopentadienone/hydroxycyclopentadienyl ligands and N‐heterocyclic carbene as ...

Phosphazene Base Mediated (sp3)C–H Functionalization with CO2 and CS2

European Journal of Inorganic Chemistry, Accepted Article.
The activation of weakly acidic (sp³)C–H bonds in substrates such as fluoroform (HCF3), perfluoroethane (HC2F5), and acetonitrile (H3CCN) remains a fundamental challenge in synthetic chemistry. We report that the phosphazene base {(Et2N)3P=N}3P=NtBu (EtP4) enables the selective deprotonation of these molecules when combined with electrophilic small ...
