Dawn of a new era? A base-metal single-atom catalyst for organic fine chemical synthesis

Single-atom catalysts (SACs) hold the potential to combine the benefits of both heterogeneous and homogeneous catalysis. In this issue of Chem, Beller and co-workers demonstrate the selective insertion of transient copper carbenes into diverse X‒H (X = C, N, O, S) bonds with excellent functional-group tolerance by using a porous Al2O3-supported SAC.

Chiral silver cluster-based light-harvesting systems: Enantioselective chirality transfer and amplified circularly polarized luminescenceYuan et al.ChemFebruary 21, 2024In BriefThe chirality-matching and -specific interactions between donors and acceptors enantioselectively facilitate chirality/energy transfer from S-/R-BPOA assembly to chiral Ag6 clusters in nanohelices, realizing efficient ET and CPET processes with amplified CPL responses. This work provides valuable new insights into chiroptical phenomena in C-LHSs and the hierarchical evolution of homochirality. Furthermore, these findings contribute to the advancement of CPL-regulated applications in areas such as information encryption and chirality detection. Full-Text PDF
