Synthese und stereoselektive Reaktionen isomerenreiner Rheniumthioaldehydkomplexe / Synthesis and Stereoselective Reactions of Isomerically Pure Rhenium Thioaldehyde Complexes

Bock, Frank January 2007 (has links) (PDF)
Diastereo- und enantiomerenreine Rheniumthioaldehydkomplexe mit stereogenem Metall und P-chiralen Phosphanliganden wurden ausgehend von [CpRe(CO)(NO)(NCCH3)]BF4 synthetisiert. Die Thioaldehydkomplexe und Zwischenprodukte wurden NMR- und IR-spektroskopisch sowie kristallographisch charakterisiert. Additionsreaktionen von C- und S-Nucleophilen an koordinierten Thiobenzaldehyd wurden insbesondere hinsichtlich ihrer Stereoselektivität untersucht. Chiral modifizierte Liganden wurden unter Rückgewinnung wiederverwendbarer Komplexvorstufen freigesetzt. / Diastereo- and enantiopure rhenium thioaldehyde complexes with stereogenic metal center and P-chiral phosphane ligands were prepared starting from [CpRe(CO)(NO)(NCCH3)]BF4. The thioaldehyde complexes and all intermediates were characterized by NMR and IR spectroscopy as well as X-Ray diffraction. The reactivity of thiobenzaldehyde complexes in nucleophilic additions was studied with regard to stereoselectivity. Chirally modified ligands were liberated.
