Summary: In this study, a 2(nd)-generation Grubbs-Hoveyda type catalyst was immobilized in mesoporous silica and used in the ring-closing metathesis (RCM) of an alpha,omega-diene to a large macro(mono)cycle. The relationship between substrate concentration, reaction time, and overall experiment time on the rate of isomerization under spatial confinement with continuous-flow microreactors was investigated. The results showed that higher substrate concentrations and longer reaction times increased the isomerization rate, while prolonged overall experiment times led to a decline in the isomerization rate.

Summary: Enyne metathesis reactions involving metallacyclobutene intermediates have been extensively studied and utilized in various synthetic processes and catalytic transformations. In this study, we investigated the utilization of metalla-aromatic in classical [2 + 2] cycloaddition, where eta(3)-allyl structures were formed stoichiometrically through hydrogen-bonding-induced [2 + 2] cycloaddition between propynol and a ruthenabenzene complex. The impact of intramolecular hydrogen bonding interaction was analyzed using experimental and computational studies.

Summary: In this study, diverse polyfunctional substrates were subjected to olefin metathesis reactions in water emulsions using hydrophobic ruthenium catalysts. Instead of using surfactants, ultrasound and microwave techniques were tested on a small scale while conventional heating and mechanical stirring were effective on a larger scale. The developed conditions allowed for low catalyst loadings and simple isolation and purification of the products. The synthetic protocol was successfully applied in the large-scale synthesis of a pharmaceutically related product, sil-denafil (Viagra) derivative.

Summary: Two new covalent triazine frameworks incorporating phenyl extended naphthalene units have been prepared using thermal and microwave activation. These frameworks show similar chemical structures but exhibit differences in morphology, structural organization, CO2 adsorption capacity, and thermal and optical properties. Additionally, the presence of methoxy groups in the naphthalene core has an influence on some of these properties. The resulting phenyl extended naphthalene CTFs are utilized as metal-free heterogeneous photocatalysts for selective reactions under visible-light irradiation, demonstrating high chemical stability.

Summary: The synthesis of macrocycles, which are cyclized organic compounds with more than ten atoms, has traditionally been limited by the need for reversible reactions under highly diluted conditions to prevent the formation of intermolecular products. However, researchers have now demonstrated that the intramolecular Mizoroki-Heck reaction of ω-iodide cinnamates can proceed at higher concentrations (1 M) when catalyzed by few-atom Pd clusters, yielding different macrocycles in good yields. This paradigm shift allows for increased macrocycle production and the use of solid catalysts in flow reactions.

Summary: In this study, four organosulfide-based covalent organic polymers (SOPs) were synthesized via click reactions, using S(N)2 or thiol-yne coupling reactions. The formation of SOPs in high yields was confirmed by solid-state C-13 NMR and FTIR spectroscopies, and the molar ratio of C : S in SOP-type materials confirmed the stoichiometric products. The SOPs exhibited high porosity, with specific surface areas up to 180 m(2) g(-1), which strongly depended on the ligands used. Additionally, the SOPs showed excellent catalytic activity in carboxylic acid esterification reactions, with high conversions and efficient recyclability. The proposed reaction mechanism involved the activation of carboxylic acids by hypervalent SMIDLINE HORIZONTAL ELLIPSISO (n(O) -> sigma(S)*) interactions with sulfur centers of the SOPs, enhancing the electrophilic character of the carboxylic carbon and facilitating alcohol addition. Therefore, SOPs represent a new class of metal-free heterogeneous Lewis acid (organo)catalysts.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
