Abstract

A series of hexanuclear 3d–4f complexes with unique structures as catalysts for CO2 fixation into cyclic carbonates under mild conditions.

Self-assembly of octanuclear Ln(iii)-based clusters: their large magnetocaloric effects and highly efficient conversion of CO2

“…Based on the recently reported mechanism of the cycloaddition of CO 2 and epoxides, [106][107][108] we explore and propose a…”

Influence of a Lanthanide Ion on the Ni Site of a Heterobimetallic 3d–4f Mabiq Complex

“…Domino, Friedel-Crafts, Mannich, Michael addition and cross-coupling reactions have all been successfully catalyzed by polynuclear 3d-4f coordination clusters. 14,15 Enhanced CO 2 transformations by asymmetric Zn-Ln complexes, [16][17][18][19] and catalytic olefin hydrogenation promoted by Ni-Lu complexes-in which lanthanide coordination was crucial for tuning and exploiting the reactivity at the Ni centerhave also been reported in the last five years. 20 Lanthanides incorporated into Mn-based water oxidation cluster mimics modulate the Mn potentials, as well as the O-atom transfer activities of these systems.…”

“…Catalysis involving 3d–4f complexes also is a quickly developing field; lanthanides can have a marked effect on both small molecule and organometallic reactions. Domino, Friedel–Crafts, Mannich, Michael addition, and cross-coupling reactions have all been successfully catalyzed by polynuclear 3d–4f coordination clusters. , Enhanced CO 2 transformations by asymmetric Zn–Ln complexes − and catalytic olefin hydrogenation promoted by Ni–Lu complexesin which lanthanide coordination was crucial for tuning and exploiting the reactivity at the Ni centerhave also been reported in the past five years . Lanthanides incorporated into Mn-based water oxidation cluster mimics modulate the Mn potentials as well as the O-atom transfer activities of these systems. , The first examples of molecular 3d–4f water oxidation catalysts (WOCs), a Co 3 Ln (Ln = Ho–Yb) cubane series reported by Evangelisti et al, also showed enhanced photocatalytic performance compared to Co-only molecular WOCs …”

Novel Cobalt Complex as an Efficient Catalyst for Converting CO2 into Cyclic Carbonates under Mild Conditions

“…The IR spectrum of 2 confirmed that the structural integrity of 2 was well maintained after catalysis (Figure 2b). The cycle of the catalytic system was successfully repeated seven times with little change in conversion (Figure 2a The recyclability and stability of a catalyst plays an integral role in practical application [24,28,29]. The recycling experiment was carried out by the optimal reaction conditions obtained under the above experiment, i.e., 60 °C and 10 bar of CO2 and 12 h. 1 mol% of the catalyst and propylene oxide were placed in an autoclave and passed through 10 bar of CO2 for 12 h to calculate the yield.…”
