Photoinduced Radical Relay Reaction of 2-Methylthiolated Phenylacetylenes/Alkynones Initiated by Electron Donor-Acceptor Complexes.

A method was found to construct sulfur-containing five- and six-membered heterocyclic alkyl sulfonyl compounds by using visible light and free radicals activated and/or generated by EDA complexes/homolytic cleavage as initiators to stimulate the relay reaction of alkynes/alkynones. This method puts forward a new strategy to initiate alkyl sulfonation of alkynes/alkynones with only a catalytic amount of the initiator. This strategy of generating the initiator by EDA complex activation/homolytic cleavage provides a new idea for the following substances that must be excited.

Reconstruction of a Closed-Loop Ecological Cycle System Anchored by Large-Scale Load-balancing Biogas and its economic viability assessment.

Biogas can be used for complementary load-balancing with renewable intermittent power, thus maintaining overall energy output stability. However, biogas load balancing load balancing is typically used in small-scale distributed energy systems, constrained by factors such as technology and land requirements, making it challenging to scale up. Therefore, this study proposes a closed-loop ecological cycle system, where biogas provides load leveling support for large-scale intermittent power sources in desertified regions dominated by animal husbandry.

Moderate-Intensity Statin Plus Ezetimibe: Time to Rethink it as an Optimal Initial Lipid-Lowering Strategy.

Achievement of low-density lipoprotein cholesterol (LDL-C) targets is crucial for the prevention of cardiovascular disease (CVD) in individuals with dyslipidaemia who are at high risk. Current guidelines recommend high-intensity statins at the highest tolerated dose as initial treatment to achieve LDL-C goals. However, the real-world situation is dismal: high-intensity statins are underused and achievement of LDL-C goals is suboptimal.

Organic Photoredox Catalytic Difluoroalkylation of Unactivated Olefins to Access Difluoro-Containing Tetrahydropyridazines.

Herein, we disclose a readily available phenothiazine derivative as an organocatalyst, which upon excitation with 371 nm light acquires a strongly reducing power and serves to induce the radical cascade difluoromethylation/cyclization reaction of -homoallylacetohydrazides. A variety of CFCOR-tetrahydropyridazines have been obtained in moderate to excellent yields. This catalytic platform proceeds under metal-free conditions with a wide substrate scope and broad functional group compatibility, which unlocks the new reactivity of phenothiazine derivatives and adds significant synthetic value to -heterocycles.
