Computed Properties of 349-88-2.
Radhoff, Niklas;Studer, Armido research published 《 1,4-Aryl migration in ketene-derived enolates by a polar-radical-crossover cascade》, the research content is summarized as follows. Here a simple, efficient and scalable method for the preparation of sterically hindered and valuable α-quaternary amides RNHC(O)C(R1)(R2)(R3) (R = i-Pr, Ph, 2,2-dimethyl-1,3-dioxan-5-yl, etc.; R1 = Me, Et, Ph; R2 = Me, Ph, 4-iodophenyl, etc; R1R2 = -(CH2)6-; R3 = Ph, 4-chlorophenyl, thiophen-2-yl, etc.) via a polar-radical crossover-enolate oxidation-aryl migration pathway was reported. A variety of easily accessible N-alkyl and N-arylsulfonamides RNHS(O)2R3 is reacted with disubstituted ketenes R1(R2)C=C=O to give the corresponding amide enolates, which undergo upon single electron transfer oxidation, a 1,4-aryl migration, desulfonylation, hydrogen atom transfer cascade to provide α-quaternary amides in good to excellent yields. Various mono- and di-substituted heteroatom-containing polycyclic arenes engage in the aryl migration reaction. Functional group tolerance is excellent and substrates as well as reagents are readily available rendering the method broadly applicable.
Computed Properties of 349-88-2, 4-Fluorobenzenesulfonyl chloride is a useful research compound. Its molecular formula is C6H4ClFO2S and its molecular weight is 194.61 g/mol. The purity is usually 95%.
4-Fluorobenzenesulfonyl Chloride is found to be an excellent activating agent for the covalent attachment of biological substances to a variety of solid supports e.g. Sepharose beads. 4-Fluorobenzenesulfonyl Chloride is also used as a reagent for the studies of proteins by fluorine NMR.
4-Fluorobenzenesulfonyl chloride is a reactive chemical that has been shown to have a low safety profile in humans. It is used in the synthesis of replication inhibitors, which are potential anticancer drugs. It also has been shown to inhibit tumor metastasis and growth in mice by binding to the active site of DNA polymerase and inhibiting DNA replication. 4-Fluorobenzenesulfonyl chloride is stable in human liver cells and has been shown to be an effective macroinitiator for proton-coupled electron transfer reactions. This compound has been shown to induce locomotor activity and energy efficiency in rats, which may be due to its ability to increase the number of mitochondria per cell., 349-88-2.
