Summary: Nowadays, the click reaction of azides with alkynes has rapidly evolved as an efficient method for synthesizing 1,2,3-triazoles, an important class of N-containing heterocycles. While the 1,4-selective click reaction is well-established, the corresponding 1,5-selective reaction remains less explored, lacking a systematic review. This timely review summarizes the discovery and development of 1,5-selective click reactions of azides with alkynes for synthesizing 1,5-substituted 1,2,3-triazoles, including three types of reactions based on critical reactive intermediates and related mechanistic studies.

Summary: Given the wide availability and low cost of alkylbenzenes, direct C-H functionalization of these aromatic hydrocarbons to afford structurally complex building blocks has long been of interest in organic synthesis. Here, we describe a method for rhodium-catalyzed dehydrogenative (3 + 2) cycloaddition reactions of alkylbenzenes with 1,1-bis(phenylsulfonyl)ethylene. The generality of this catalytic method was demonstrated by carrying out reactions of a large array of alkylbenzenes to generate dihydroindene derivatives bearing two synthetically versatile sulfonyl groups.

Summary: Irradiating cobalt metallocenes at specific energies causes the destabilization of the cyclopentadienyl-cobalt bond and the release of radicals. These radicals can be detected by EPR spectroscopy and chemically captured using hydrogen-atom-donating reagents. This reaction offers a new photochemical method for generating cobalt complexes or catalytic cyclopentadienyl cobalt(I) species for [2 + 2 + 2] cyclotrimerization reactions. Additionally, the results highlight that cobaltocene is not a photostable redox reagent under various conditions, including those relevant to photovoltaics or photocatalysis.

Summary: A new method for synthesizing pure organic photoluminescent molecules with dual excited-state intramolecular proton transfer (ESIPT) sites was developed. These molecules can emit full-color light from blue, green, and yellow to red, and even white light, depending on the solvents used. The study verified the dual-ESIPT mechanism through experiments on copper ions' selective photoluminescent response and solid-state photoluminescent changes upon the stimulus of organic vapor. Theoretical analysis further supported the experimental results and provided insights for the design and application of advanced dual-ESIPT optical materials.

Summary: This article discloses a catalyst type that enables highly efficient direct 1,4-additions. The catalyst is a zwitterionic entity, with acetate binding to negatively charged Cu-II and serving as a counterion for benzimidazolium. All three functionalities are involved in the catalytic activation. The productivity of maleimides increased by a factor greater than 300 compared to the literature (TONs up to 6700). High stereoselectivity and productivity were achieved for a wide range of other Michael acceptors as well. The polyfunctional catalyst, accessible in only 4 steps from N-Ph-benzimidazole with an overall yield of 96%, remained robust during catalysis, allowing for multiple reuse with nearly constant efficiency. Mechanistic studies, particularly using DFT, provided a detailed understanding of how the catalyst operates. The benzimidazolium unit stabilizes the coordinated enolate nucleophile and prevents the dissociation of acetate/acetic acid from the catalyst.

Summary: We synthesized and characterized Cu(ii) complexes CuL1-CuL6 with cyclen-based ligands. The ligands L-1-L-6 comprise different donor sets including S and O atoms. The substitution of N donor atoms with hard donor O atoms leads to efficient oxidative nucleases, but dissociation of the complex upon reduction. We are showing that the rational combination of O and S atoms next to two nitrogen donors within the macrocycle leads to the stabilization of both redox states, resulting in the highest oxidative DNA cleavage activity within this family of cyclen-based Cu(ii) complexes.

Summary: A visible light photosensitizing metal-organic cage is used as an artificial supramolecular reactor to control the reaction of aryl radicals with terminal olefins, resulting in the selective transformation of geometrically defined E/Z-alkenes. The hydrophobic cage efficiently includes aromatic substrates, promoting Meerwein arylation and protecting E-isomeric products, while benzonitrile induces efficient E -> Z isomerization. In addition to pi-pi stacking, hydrogen bonding and halogen bonding interactions play a role in controlling the arylation of aliphatic terminal olefins. This switchable cage-confined arylation catalysis has been demonstrated in the syntheses of Tapinarof and a marine natural product, achieving controllable E/Z selectivity.

Summary: Two homoleptic Fe(II) complexes with superbasic terpyridine derivatives as ligands were studied to investigate the relationship between spin state and electrochemical/spectroscopic behavior. Antiferromagnetic coupling between a ligand-centered radical and the high-spin metal center resulted in an anodic shift of the first reduction potential and a mixed valency species with a moderately intense intervalence-charge-transfer band. The different spin states also influenced the electrochemical reactivity, with the low-spin species acting as a precatalyst for electrocatalytic CO2 reduction and showing a Faradaic efficiency of 37% for CO formation, while the high-spin species only catalyzed proton reduction with a modest Faradaic efficiency of approximately 20%.

Summary: The host-guest interaction and microenvironment around the Re complex in two metal-organic frameworks, ZIF-8 and UiO-66, were investigated. It was found that ZIF-8 provided a confined space for Re through electrostatic interaction, while UiO-66 offered a relaxed space through coordination interaction. The Re@ZIF-8 exhibited a significantly higher turnover number for CO2 photoreduction compared to Re@UiO-66, which was attributed to the promotion of electron transfer in Re@ZIF-8 and hindrance in Re@UiO-66. The spatial confinement in Re@ZIF-8 stabilized charged intermediate species during CO2 activation, whereas Re-triethanolamine adducts prevailed in Re@UiO-66 due to the accessibility of the Re complex. This study demonstrates the feasibility of altering CO2 activation pathway through the microenvironment of a molecular catalyst in artificial photosynthesis.

Summary: Photocatalytic reduction of excess CO2 in the atmosphere to value-added chemicals by visible light can be achieved using a trinuclear Re(I)-coordinated organic cage (Re-C-4(R)) as the supramolecular photocatalyst. The Re-C-4(R) exhibits higher catalytic activity and CO2 adsorption ability compared to its mononuclear analogue Re-bpy, due to its covalent linkage, cryptand structure, and multiple amine groups. The trinuclear cryptate structure of Re-C-4(R) also facilitates electron transfer efficiency during CO2 reduction, as indicated by its shorter decay lifetimes in transient absorption and photoluminescence decay spectra compared to Re-bpy.
