4. 3. Non Natural Aromatic Amino Acids Applications in cage-construction, metal ion coordination and asymmetric catalysis

   Författare :Ruxandra Ionescu; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diethylzinc additions.; spectroscopy; metal ion coordination; cage-like compounds; Amino acids; C3-symmetry; Organic chemistry; Organisk kemi;

   Sammanfattning : Aromatic non-natural amino acids, the outstanding feature of which was the presence of several arms, were synthesised and their properties investigated. The amino acids were synthesised following a standard procedure starting with a Horner-Wadsworth-Emmons or a Heck reaction, which provided didehydroamino acids. LÄS MER

5. 4. Structural and Spectroscopic Studies of Solvated Metal Ions

   Författare :Alireza Abbasi; Magnus Sandström; Ernö Brucher; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination; Solvation; X-ray diffraction; EXAFS; IR; Raman; Normal coordinate analysis; trivalent metal ions; dmso; triflate; hydration; Chemistry; Kemi;

   Sammanfattning : Crystallographic and spectroscopic studies have been performed of structures, coordination and chemical bonding for series of trivalent metal ions solvated by two oxygen-coordinating solvents, water and dimethyl sulfoxide (DMSO). The hydrated scandium(III) and lanthanoid(III) ions, La to Lu, are surrounded by tricapped trigonal prisms of aqua ligands in the isomorphous series of trifluoromethanesulfonates, [M(H2O)n](CF3SO3)3.
