[Zinc(II)(Pyridine‐Containing Ligand)] Complexes as Single‐Component Efficient Catalyst for Chemical Fixation of CO <sub>2</sub> with Epoxides
نویسندگان
چکیده
The reaction between epoxides and CO2 to yield cyclic carbonates is efficiently promoted under solvent-free relatively mild conditions (0.5 mol % catalyst loading, 0.8 MPa, 125 °C) by zinc(II) complexes of pyridine containing macrocyclic ligands (Pc−L pyridinophanes). zinc have been fully characterized, including X-ray structural determination. [Zn(II)X(Pc−L)]X showed good solubility in several polar solvents, carbonates. scope the has studied quantitative conversions with excellent selectivities obtained, starting from terminal epoxides. When were not possible (solid or low oxirane) use as solvents successfully investigated. remarkable stability catalytic system demonstrated a series consecutive runs.

A single-site hydroxyapatite-bound zinc catalyst for highly efficient chemical fixation of carbon dioxide with epoxides.
A zinc-based hydroxyapatite catalyst in conjunction with a Lewis base proved to be efficient for the coupling of CO2 and epoxide in the absence of additional organic solvents under an atmospheric CO2 pressure; the work-up procedure is straightforward and the catalyst could be reused without loss of catalytic activity and selectivity.

Covalent grafting of MCM-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with MoO2(acac)2 afforded MoO2acacdien@MCM-41. X-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as well as accessibility of the channel system despite sequential reduction in surface area, pore vo...
