Lithiating
WebLithiation refers to the process by which a lithium atom replaces a hydrogen atom in an organic molecule. The resultant molecule is described as an organolithium compound. The C-Li bond is highly polarized, the carbon atom is electron rich, and therefore organolithium compounds are strongly basic and nucleophilic. Web2 dagen geleden · Despite recent advancements in the development of catalytic asymmetric electrophile induced lactonization reactions of olefinic carboxylic acids, the archetypical hydrolactonization has long remained an unsolved and well-recognized challenge. Here, we report the realization of a catalytic asymmetric hydrolactonization using a confined …

WebElectrochemical insertion/extraction of Li cations for compound 1 is performed in a half cell using 1 M LiClO 4 in propylene carbonate as an electrolyte and Li metal as a counterelectrode. Compound 1 is used as the working electrode, and Li metal is used as both the counter and working electrodes. In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for a…
WebLignin-based carbon fibers (LCFs) from the renewable resource softwood kraft lignin were synthesized via oxidative thermostabilization of rein melt-spun lignin and carbonization at different temperatures from 1000°C to 1700°C. The result LCFs were characterized by tensile exam, scanning electron microscopy (SEM), X-ray lens (XRD) and confocal … WebThis paper compares and combines two common methods to improve the cycle performance of lithium metal (Li) electrodes. One technique is to establish a micro-structured current collector by chemical separation of a copper/zinc alloy. Furthermore, the use of a highly concentrated ether-based electrolyte is applied as a second approach for …
