In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called An unusually stable octanuclear σ-mesityl-bridged μ4-oxo-copper(I) complex encapsulated by a pyrazolate-based compartmental ligand scaffold, published in 2008-04-21, which mentions a compound: 75732-01-3, mainly applied to copper octanuclear mesityl oxo bridged pyridine amine pyrazolate preparation; arylcopper oxo bridged pyrazolate aminomethylpyridine octanuclear complex preparation structure; crystal structure arylcopper oxo bridged pyrazolate aminomethylpyridine octanuclear complex; mol structure arylcopper oxo bridged pyrazolate aminomethylpyridine octanuclear complex, Application In Synthesis of Mesitylcopper(I).
Reaction of a new compartmental pyrazole-derived hexadentate chelating ligand 4-Ph-3,5-(C5H4N-2-CH2NMeCH2)2 (2, HL) with four equiv of mesitylcopper and stoichiometric amounts of dioxygen lead to the formation of a remarkably stable organometallic framework [[(μ-L)Cu2]2(μ-mesityl)4Cu4(μ4-O)] (3, shown as I) that can be described as a heteroleptic O-centered cuprate anion [(MesCuI)4(μ4-O)]2- linked via σ-mesityl-bridges to two surrounding binuclear CuI-pyrazolate clamps.
I hope my short article helps more people learn about this compound(Mesitylcopper(I))Application In Synthesis of Mesitylcopper(I). Apart from the compound(75732-01-3), you can read my other articles to know other related compounds.
