Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about An unusually stable octanuclear σ-mesityl-bridged μ4-oxo-copper(I) complex encapsulated by a pyrazolate-based compartmental ligand scaffold.Recommanded Product: 75732-01-3.
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.
