The author of the article were Auvray, Thomas; Pal, Amlan K.; Hanan, Garry S.. The article conveys some information:
Re(I) tricarbonyl complexes were synthesized using bi- and tridentate ligands equipped with one or two hexahydro-pyrimidopyrimidine (hpp) units attached to either a pyridine or a pyrazine ring. These complexes were characterized by NMR, ESI-MS, vibrational and optical spectroscopies as well as electrochem. Their structures were determined via single-crystal x-ray crystallog. and modelled using both DFT and TD-DFT methods. The complexes are non-emissive in solution at room temperature but display emission with mixed intra ligand (major) and metal-ligand (minor) charge transfer characters at 77 K. Addnl., both pyrazine-based complexes appear to be emissive in the solid state, presumably due to the presence of intermol. interactions, as observed in the crystal structure. In the experiment, the researchers used many compounds, for example, 2,6-Dibromopyridine(cas: 626-05-1Application In Synthesis of 2,6-Dibromopyridine)
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Application In Synthesis of 2,6-Dibromopyridine
