Abstract

Structure of chiral complexes of ytterbium triflate with R11′bi2naphthol and 1234diOisopropylideneαdgalactopyranose highly effective catalysts in enantioselective cycloaddition reaction of 4trifluoromethylbenzonitrile oxide to Z2pentenol and 2methoxyphenylcrotonamide was examined with the application of electron paramagnetic resonance EPR 1H 13C 19F nuclear magnetic resonance infrared spectroscopy mass spectroscopy and spectrofluorimetry EPR spectroscopy has demonstrated the presence of the octahedral and tetrahedral environments of the complexes Observation of strong emission bands proved electron delocalization to the remote areas which enabled an interaction of the ligand with the rest of the catalytic complexThis work was supported in part by the Polish Ministry of Science and Higher Education Research grant no N209 003 638 which is gratefully acknowledged We also thank prof Wiktor Koźminski and dr Marcin Wilczek from Department of Chemistry University of Warsaw Poland and dr Pavlo Aleshkevych Institute of Physics Polish Academy of Sciences Warsaw Poland for words of advice
