2-Chlorobenzothiazole (cas: 615-20-3) belongs to thiazole derivatives. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Name: 2-Chlorobenzothiazole

The newly prepared unsym. PCN-pincer ligand with a benzothiazole side-arm 2-(3-((di-tert-butylphosphino)methyl)phenoxy)benzothiazole [BzTz(H)PCN] has been cyclometalated with anhydrous NiBr2 to get the corresponding NiII square planar bromo complex [(BzTzPCN)NiBr] (1) after HBr elimination and C-H activation on the pincer central Ph ring. Starting from 1, reaction with AgF in toluene or with AgBF4 in THF led to bromide abstraction and formation of the fluoro complex [(BzTzPCN)NiF] (2) and the ionic aqua species [(BzTzPCN)Ni(H2O)][BF4] (3), resp. All species have been characterized in solution (multinuclear 1H, 13C{1H}, 31P{1H} and 11B NMR spectroscopy) and in the solid state (single-crystal X-ray diffraction anal.). Finally, comparative electrochem. measurements (CV and in situ EPR-spectroelectrochem.) carried out on the halide complexes 1 and 2 revealed that the anodic oxidation process leads to the formation of stable NiIII species bearing a coordinated bromide ligand in case of 1 and a fluoride-free complex in case of 2. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzothiazole (cas: 615-20-3Name: 2-Chlorobenzothiazole).
