Synthesis and reactivity of palladium(II) fluoride complexes containing nitrogen-donor ligands

This article describes the synthesis, characterization, and reactivity of palladium(II) fluoride complexes containing sp(2) and sp(3) nitrogen-containing supporting ligands. Both cis and trans complexes of general structure (N)(N')Pd-II(R)(F) (R = Ar or CH3) as well as cis-(N)(2)Pd-II(F)(2) are reported. Crystallographic characterization of these molecules has allowed structural comparisons to related phosphine-ligated species. Furthermore, these studies have revealed that nitrogen-donor ligands support some of the longest and the shortest Pd-F bonds reported to date. The thermal decomposition of (N)(N')Pd-II(R)(F) has also been examined, and no products of C-F bond-forming reductive elimination were obtained in any case.
