ortho-substitution is highlighted by the comparison of the aurophilic interactions in Au2Cl2(o-R,R-DPEphos) and the hydrogenation product from [Rh(o-R,R-DPEhphos)(NBD)][BArF4] complexes (R=H or F). An unexpected dicationic dimer of o-H,H-DPEphos with an agostic C−H group is revealed for the latter.
已合成邻氟取代的 DPEphos 配体:o -F , F-DPEphos。通过比较 Au 2 Cl 2 (oR,R-DPEphos) 和 [Rh( o -R,R-DPEhphos)(NBD)] [ BAr F 4 ] 配合物(R=H或F)。后者揭示了一个意想不到的o -H,H-DPEphos 的双阳离子二聚体,带有一个抑制的 C-H 基团。
