Diese Studie beschreibt die Konzipierung und Implementierung einer neuen Prüfungsform in der notfallmedizinischen Studentenausbildung, die die Anforderungen an eine moderne Prüfung erfüllt. Am Ende des Kurses „Akute Notfälle und Erste Ärztliche Hilfe“ nahmen 32 Studenten am Probelauf eines Prüfungsparcours im Sinne eines Objective Structured Clinical(More)
Activating chemical bonds through external triggers and understanding the underlying mechanism are at the heart of developing molecules with catalytic and switchable functions. Thermal, photochemical, and electrochemical bond activation pathways are useful for many chemical reactions. In this Article, a series of Ru(II) complexes containing a bidentate and(More)
Reversible proton- and electron-transfer steps are crucial for various chemical transformations. The electron-reservoir behavior of redox non-innocent ligands and the proton-reservoir behavior of chemically non-innocent ligands can be cooperatively utilized for substrate bond activation. Although site-decoupled proton- and electron-transfer steps are often(More)
The zinc-catalyzed addition of various alkynes to acylsilanes followed by a Zn-Brook rearrangement and either the Zn-ene-allene or Zn-yne-allene cyclization led to the enantio- and diastereoselective formation of carbocycles in a single-pot operation.
Electrochemical and photochemical bond-activation steps are important for a variety of chemical transformations. We present here four new complexes, [Ru(L(n) )(dmso)(Cl)]PF6 (1-4), where L(n) is a tripodal amine ligand with 4-n pyridylmethyl arms and n-1 triazolylmethyl arms. Structural comparisons show that the triazoles bind closer to the Ru center than(More)
Tuning of ligand properties is at the heart of influencing chemical reactivity and generating tailor-made catalysts. Herein, three series of complexes [Ru(L)(Cl)(X)]PF6 (X=DMSO, PPh3 , or CD3 CN) with tripodal ligands (L1-L5) containing pyridine and triazole arms are presented. Triazole-for-pyridine substitution and the substituent at the triazole(More)
Reactions of [{Ru(tmpa)}2(μ-Cl)2][ClO4]2, (2[ClO4]2, tmpa=tris(2-pyridylmethyl)amine) with 2,5-dihydroxy-1,4-benzoquinone (L1), 2,5-di-[2,6-(dimethyl)-anilino]-1,4-benzoquinone (L2), or 2,5-di-[2,4,6-(trimethyl)-anilino)]-1,4-benzoquinone (L3) in the presence of a base led to the formation of the dinuclear complexes [{Ru(tmpa)}2(μ-L1-2H)][ClO4]2 (3[ClO4]2),(More)
The course in emergency medicine was introduced by the German Federal Government to meet the requirements of the curriculum of the 4th year of medical education in 1992. The Department of Anaesthesiology of the University Hospital Ulm drew up a course consisting of one week of practical instructions (Table 3) for groups of 24 students, case presentation and(More)
