Reference of Mesitylcopper(I). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Direct Catalytic Asymmetric Aldol Reaction of α-Alkylamides. Author is Liu, Zijian; Takeuchi, Toshifumi; Pluta, Roman; Arteaga Arteaga, Fernando; Kumagai, Naoya; Shibasaki, Masakatsu.

A catalytic asym. aldol reaction directly employing amides as latent enolates has remained elusive because of the resistance of amides to enolization. A direct aldol reaction of α-alkylamides without any electron-withdrawing group harnessed by specific activation of 7-azaindoline amides under soft Lewis acid/Bronsted base cooperative catalysis is reported. Diastereo- and enantioselective coupling with ynals and aromatic aldehydes as well as divergent functional group interconversion of the amide provided expeditious access to a variety of aliphatic and aromatic chiral building blocks.

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 bimetallic nanoparticles in ionic liquids: Chemical routes vs physical vapor deposition.Computed Properties of C9H11Cu.

Ionic liquids (ILs) can be used to generate and stabilize metallic nanoparticles (MNPs) by several phys. and chem. routes. Here, the simultaneous decomposition of Ru and Cu organometallic precursors in IL is shown to yield core-shell Ru@CuNPs with smaller diameters and narrower size distributions than the corresponding monometallic NPs, in a broad range of Ru:Cu compositions They are probably formed by rapid nucleation of Ru cores followed by decomposition of the Cu precursor on their surface. This effect forces the formation of a bimetallic structure that does not form with the use of purely phys. processes such as PVD. These Cu, Ru, and Ru@CuNPs could be used for the formation of seed and barrier layers for the metalization of advanced interconnect structures.
