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 Synthesis of novel copper-rare earth BINOLate frameworks from a hydrogen bonding DBU-H rare earth BINOLate complex.Safety of Mesitylcopper(I).
The preparation of a novel H-bonding DBU-H+ BINOLate Rare Earth Metal complex [RE(S-binol)3ยท3DBU-H, where RE = La, Pr, and Eu; DBU = 1,8-Diazabicyclo(5.4.0)undec-7-ene] enabled the synthesis of the first copper-Rare Earth Metal BINOLate complex (CuDBU-REMB, Cu3RE(S-binol)3(DBU)3). CuDBU-REMB was compared to the analogous Li complex using x-ray crystallog. and Exchange NMR spectroscopy (EXSY). The results provide insight into the role of the secondary metal cation in the framework’s stabilization.
