"Super hybrid tridentate ligands": 4-substituted-2-(1-butyl-1H-1, 2,3-triazol-4-yl)-6-(1H-pyrazol-1-yl)pyridine ligands coordinated to Fe(ii) ions display above room temperature spin transitions

A series of novel "super hybrid tridentate ligands" based on (2-(1-butyl-1H-1,2,3-triazol-4-yl)-6-(1H-pyrazol-1-yl)pyridine (tpp) derivatives were synthesized. Their Fe(ii) complexes display around (T = 287 K) and above room temperature (T ? 375 K) spin transition temperatures.
6,6′-dibromo-4,4′-di(hexoxymethyl)-2,2′-bipyridine: A new solubilizing building block for macromolecular and supramolecular applications

Although brominated bipyridines and terpyridines are highly desirable synthetic building blocks for both ligand design and macro- or supramolecular applications, few such synthetic precursors have been reported that include much-needed solubilizing groups. Reported here is an inexpensive route to 2,6-dibromo-4-(hexoxymethyl)pyridine from citrazinic acid with an overall yield of 44% and its efficient conversion (60%) to 6,6′-dibromo-4,4′- di(hexoxymethyl)-2,2′-bipyridine via oxidative coupling.

Electronic tuning by para substitutions was explored to achieve a highly active manganese N-heterocyclic carbene pincer complex for the selective electrocatalytic reduction of CO2 to CO. [MnCNCOMe]BF4 (L2-Mn) bearing an electron-donating group (–OMe) showed high activity with 63 × catalytic current enhancement, average Faradaic efficiency of 104%, and a TOFmax value of 26,127 s?1, which is 127 times higher than that of unsubstituted [MnCNCH]Br (L1-Mn) reported previously. In contrast, the electron-withdrawing group (–COOMe) in [MnCNCCOOMe]PF6 (L3-Mn) inhibited the electrocatalytic activity. Ambient Br?nstic acid, however, suppressed the activity of L2-Mn probably due to the protonation of the –OMe group. These findings indicate a potential electronic tuning strategy to improved manganese N-heterocyclic carbene catalysts for CO2 reduction.
