Comprehensive Summary The EDA complex‐mediated reactions involving oxime esters have been few studied. Herein, an complex formed by thiophenolate anion and ester is reported for photoinduced divergent synthesis of thioethers, depending on different types esters. Operational simplicity, mild reaction conditions, flexible options leaving group demonstrate the generality synthetic utility this approach. Such approach can also enable interesting thiol‐catalysis phenanthridines.

Abstract Fabricating visible‐light‐responsive metal−organic frameworks (MOFs) with high stability and effective catalytic functionality remains a long‐term pursuit yet great challenge. Herein, strategy of increasing ligand cluster connectivity is developed to construct highly stable fluorescein MOFs, La‐CFL, presenting new (4,8)‐connected topological structure compared Cd‐FL constructed using 6‐connected dinuclear clusters 3‐connected tritopic ligands. La 8 (CFL) 4 containers like Chinese “Ritual Wine Vessels (Jue)” resemble linear arrangements interconnected by the [La 2 (COO) ] clusters. This arrangement induces benzene rings xanthene locate on inner walls 1D channels, resulting in thicker channel that contribute enhanced stability. Consequently, La‐CFL demonstrates outstanding performance thiol–ene reactions under green LED irradiation. It exhibits 2.3 times higher efficiency than while reducing reaction time one‐fifth at 20 min. Furthermore, displays size‐selective catalysis retains full activity for cycles without degradation, an improvement over Cd‐FL's recyclability limitations.
