A simple and robust method for electrochemical alkyl C–H fluorination is presented. Using a nitrate additive, widely available fluorine source (Selectfluor), carbon-based electrodes, wide variety of activated unactivated bonds are converted into their C–F congeners. The scalability the reaction also demonstrated with 100 gram preparation fluorovaline.
Polymerization-induced self-assembly (PISA) has been established as a powerful strategy for fabrication of polymeric nano-objects in the past decade. However, comparison with traditional method, PISA is unsatisfactory preparation vesicles chemical versatility membrane-forming block tunable membrane properties, which limits further application PISA-based vesicles. Besides stimuli-responsive property, structural integrity another important concern material applications. In situ cross-linking...
Abstract We report the development of photoredox‐catalyzed and copper‐promoted trifluoromethoxylation arenediazonium tetrafluoroborates, with trifluoromethyl arylsulfonate (TFMS) as reagent. This new method takes advantage visible‐light photoredox catalysis to generate aryl radical under mild conditions, combined selective trifluoromethoxylation. The reaction is scalable, tolerates a wide range functional groups, proceeds regioselectively conditions. Furthermore, mechanistic studies...
Significance The combination of two newly emerging methods for chemical synthesis enables access to molecular space that was previously challenging or impossible access. Thus, a C–H activation ubiquitous carboxylic acids followed by their decarboxylative functionalization provides modular difunctionalized carbon frameworks with distinctly controlled stereochemistry. Application this strategy simplify the medicinally important entities and discover potent antimalarial compounds is described.
Polybutylene succinate (PBS) is a biodegradable aliphatic polyester with excellent thermal stability, mechanical properties, and processability. The synthesis of PBS typically employs titanium-based catalysts like tetrabutyl titanate (TBT) to accelerate the reaction. However, TBT acts as homogeneous catalyst non-recyclable. This study aims minimize cost recovering liquid during by using TBT-loaded activated carbon for direct esterification optimizing process conditions. was analyzed...
Abstract Polymerization‐induced self‐assembly has been demonstrated to be a powerful strategy for fabricating polymeric nanoparticles in the last two decades. However, stringent requirements monomers greatly limit chemical versatility of PISA‐based functional and expanding monomer family PISA is still highly desirable. Herein, camptothecin analogue (CPTM) first used as PISA. Prodrug with reduction‐responsive release behavior are fabricated at 10% solid concentration (100 mg g −1 )....
A near-infrared (NIR) light induced controlled cationic polymerization is presented here. The halide abstraction reaction between the cyclopentadienyl iron dicarbonyl dimer (Fe2(Cp)2(CO)4) and an organic utilized to generate initial radicals or cations under mild conditions, which can be further combined with both radical reversible addition-fragmentation chain transfer (RAFT) polymerization. Well-defined poly(vinyl ether)s polyacrylates are prepared successfully NIR by this method....
Abstract Polymer molecular weight distribution (MWD) is a key parameter of polymers. Here we present robust method for controlling polymer MWD in controlled cationic polymerizations. A latent mediator strategy was designed and combined with temporal programming to regenerate mediators at different times during polymerization. Both the breadths shapes curves were tuned easily by adjusting an external light source. Bimodal, trimodal, tetramodal distributions obtained, could be varied from 1.06...
Abstract As the prevalence of diabetes continues to increase, number individuals living with complications will reach an unprecedented magnitude. Continuous use some synthetic agents reduce blood glucose levels causes severe side effects, and thus, demand for nontoxic, affordable drugs persists. Naturally occurring compounds, such as iminosugars derived from mulberry (Morus spp.), have been shown levels. In mulberry, 1-deoxynojirimycin (DNJ) is predominant iminosugar. However, mechanism...
