The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Mesitylcopper(I)( cas:75732-01-3 ) is researched.Synthetic Route of C9H11Cu.Zou, Wenxing; Zhu, Qihao; Fettinger, James C.; Power, Philip P. published the article 《Dimeric Copper and Lithium Thiolates: Comparison of Copper Thiolates with Their Lithium Congeners》 about this compound( cas:75732-01-3 ) in Inorganic Chemistry. Keywords: copper lithium thiolate dimeric complex preparation; crystal structure copper lithium thiolate dimeric complex. Let’s learn more about this compound (cas:75732-01-3).
The direct reactions of the large terphenyl thiols HSAriPr4 (AriPr4 = -C6H3-2,6-(C6H3-2,6-iPr2)2) and HSAriPr6 (AriPr6 = -C6H3-2,6-(C6H2-2,4,6-iPr3)2) with stoichiometric amounts of mesitylcopper(I) in THF at ca. 80°C afforded the first well-characterized dimeric copper thiolato species {CuSAriPr4}2 (1) and {CuSAriPr6}2 (2) with elimination of mesitylene. The complexes 1 and 2 were characterized by NMR and electronic spectroscopy as well as by X-ray crystallog. They have dimeric Cu2S2 core structures in which the two copper atoms are bridged by the sulfurs from the thiolato ligands and feature short Cu…Cu distances near 2.4 Å as well as a weak copper-flanking aryl ring interaction from a terphenyl substituent. The structures of the planar Cu2S2 cores bear a resemblance to the Cu-A site in nitrous oxide reductase in which two cysteines also bridge two copper atoms. The related dimeric Li2S2 structural motif was also observed in the lithium congeners {LiSAriPr4}2 (3) and {LiSAriPr6}2 (4) which were synthesized directly from the thiols and n-BuLi in hexanes. However, despite the very similar effective ionic radii of the Li+ (0.59 Å) and Cu+ (0.60 Å) ions, the Li…Li structures display very much longer (by more than ca. 0.5 Å) separations than the corresponding Cu…Cu distances in 1 and 2, which may be due to weaker dispersion interactions.
