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 CH(3)) 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.
本文描述了含有 sp(2)和 sp(3)含氮支撑配体的钯(II)氟化物配合物的合成、表征和反应性。报道了具有一般结构(N)(N')Pd(II)(R)(F)(R = Ar 或 CH(3))的顺式和反式配合物以及顺式-(N)(2)Pd(II)(F)(2)。这些分子的晶体学表征允许与相关膦配体物种进行结构比较。此外,这些研究表明,氮供体配体支持迄今为止报道的最长和最短的 Pd-F 键之一。还研究了(N)(N')Pd(II)(R)(F)的热分解,但在任何情况下都没有获得形成 C-F 键的还原消除产物。
