Evaluating the electronic properties of ditopic and hetero-ditopic ligands derived from benzimidazole and pyrazole by C-13 NMR spectroscopy
Huynh’s electronic parameter (HEP) was applied to distinguish the electronic properties of benzimidazole and pyrazole donors in (NN)-N-boolean AND ditopic and (NN)-N-boolean AND’ hetero-ditopic, dinucleating ligands by C-13 NMR spectroscopy of their dipalladium complexes bearing terminal Pr-i(2)-bimy reporter ligands. The C-13(carbene) NMR resonances of the Pr-i(2)-bimy ligand (HEPs) indicate stronger donation of the symmetrical dibenzimidazole compared to that of the dipyrazole with a Delta HEP value of 1.5(4) ppm. Based on this benchmark value, the effect of spacer groups on the electron donation of the mixed benzimidazole-pyrazole ligands was investigated for the first time. The donicity gap between the benzimidazole and pyrazole donors increases with alkylene spacers, but shrinks with the 1,4-phenylene linker, suggesting electronic communication between the two different heterocycles via pi-electron conjugation. Furthermore, these complex probes could also be used to catalyze the direct arylation of pentafluorobenzene, which showed that the unsymmetrically bridged, dinuclear complexes with alkylene linkers are more reactive.
