Belgium has a vibrant health eco-system, with world-class universities and hospitals, and a strong presence of pharmaceutical companies, resulting in a substantial contribution to drug development and a high number of clinical trials. Talent development is pivotal for further growth of this eco-system and to attract future professionals. Although physicians play an important role in this complex eco-system, with an estimated 400-450 Belgian physicians presently active in the field of the drug life cycle, Pharmaceutical Medicine and Clinical Pharmacology were not recognized as a speciality in Belgium until recently.

Systematic reviews (SR) synthesize evidence-based medical literature, but they involve labor-intensive manual article screening. Large language models (LLMs) can select relevant literature, but their quality and efficacy are still being determined compared to humans. We evaluated the overlap between title- and abstract-based selected articles of 18 different LLMs and human-selected articles for three SR.

A cationic N-heterocyclic phosphenium (NHP) iron tetracarbonyl complex was synthesised from the free cation and its behaviour towards various anionic reactants studied. Reactions with fluoride, chloride, and hydride sources proceeded under attachment of the anion at phosphorus to yield Fe(CO)-complexes of neutral diazaphospholenes, while bromide and iodide reacted under addition of the anion at the metal and decarbonylation to yield NHP iron halides. Reactions with amides and organometallics were unselective.
