Fine electronic state tuning of cobaltadithiolene complexes by substituent groups on the benzene ring was written by Tsukada, Satoru;Kondo, Masataka;Sato, Hironobu;Gunji, Takahiro. And the article was included in Polyhedron in 2016.Electric Literature of C6H3F2I This article mentions the following:
A series of 3,6- and 4,5-dihalogen-substituted 1,2-benzenedithiol (H2bdt) ligands, (3,6-X12-4,5-X22-1,2-H2bdt) (X2 = H, X1 = F (1a), Cl (1b), Br (1c); X1 = H, X2 = Cl (4)), and their cobalt complexes, [Cp*Co(3,6-X12-4,5-X22-1,2-bdt)] (X2 = H, X1 = F (2a), Cl (2b), Br (2c); X1 = H, X2 = Cl (5)), were synthesized by a modified selective thiolation reaction. The 1,2-diphenyl-substituted cobaltadithiolene complex (2d) was also synthesized. The mol. structures of all cobaltadithiolene complexes were determined by single crystal X-ray diffraction anal. Compounds 2a, 5 and 12 showed unique packing structures with intermol. interactions that confirmed them as the first examples of half-sandwich-type metalladithiolene complexes with a Cp* ligand. The effects of the benzene substituent type and position on the metalladithiolene ring were investigated using UV-vis spectroscopy measurements and cyclic voltammetry. The results indicate that substitution of halogen atoms at the 3 and 6 position of the benzene ring had a larger effect on the dithiolene ring than substitution at the 4 and 5 positions. In the experiment, the researchers used many compounds, for example, 1,2-Difluoro-3-iodobenzene (cas: 64248-57-3Electric Literature of C6H3F2I).
1,2-Difluoro-3-iodobenzene (cas: 64248-57-3) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Electric Literature of C6H3F2I
