Sažetak

The deuterium isotope effect in the gas phase ligation of niobium (Nb) monocations by a mixture of pyrene and perdeutero pyrene was studied in a FTMS instrument. The attachment of pyrene (pyrene-d10) is followed by a rapid release of hydrogen (deuterium) from the Nb-pyrene (Nb-pyrene-d10) cation, respectively. The dehydrogenated product formation depends on the experimental conditions in the reaction chamber. A 1,2-elimination of H2 (D2) from the ligation product is proposed.
