Chemical Research Letters, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.4923-87-9, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4923-87-9, Name is 5-Bromobenzothiophene, molecular formula is C8H5BrS

A direct, metal-free, and oxidant-free method for the graphene oxide (GO)-catalyzed iodination of arenes and ketones with iodine in a neutral medium was explored. This iodination protocol was performed by using a simple technique to avoid the use of external metal catalysts and oxidants and harsh acidic/basic reaction conditions. In addition, by this method the degree of iodination could be controlled, and the reaction was scalable and compatible with air. This strategy opens a new field for GO-catalyzed chemistry and provides an avenue for the convenient direct iodination of arenes and ketones.

An efficient and generally applicable protocol for the palladacycle- catalyzed arylation of diisopropyl H-phosphonate in water was developed. The remarkable features of this C-P bond-forming reaction include wide substrate scope including the inactive electron-rich and electron-neutral aryl chlorides, the weak inorganic base KF instead of strong bases such as KOtBu or NaOtBu for the activation of C-Cl bond, and the addition of isopropanol to avoid the decomposition of diisopropyl H-phosphonate.

We have developed a metal and halogen-free Friedel?Crafts acylation protocol with virtually no waste stream generation. We propose a hydrogen bonding donor solvent will form a hydrogen bonding network and may provide significant rate enhancement for Friedel?Crafts reactions. Trifluoroacetic acid is one of the strongest H-bond donor solvents, which is also volatile and can be easily recovered by distillation without need for reaction workup. Our protocol is a ?green? Friedel?Crafts acylation process: 1) the catalyst can be recovered and reused; 2) using halogen free starting material (carboxylic acids anhydride or carboxylic acids); 3) no need for aqueous reaction work-up; 4) minimum or no waste steam generation.

Direct arylation of cyclopentanones has been a long-standing challenge because of competitive self-aldol condensation and multiple arylations. Reported herein is a direct mono-alpha-C-H arylation of cyclopentanones with aryl bromides which is enabled by palladium/amine cooperative catalysis. This method is scalable and chemoselective with broad functional-group tolerance. Application to controlled sequential arylation of cyclopentanones has been also demonstrated. Be direct: A direct alpha-C-H arylation of normal cyclopentanones with aryl bromides, enabled by palladium/amine cooperative catalysis, features an exceptionally high selectivity for monoarylation, use of readily available starting materials, good scalability, and broad functional-group tolerance.

Abstract: Cu2O/2,6-bis(2-methylhydrazine-1-carbonyl)pyridine 1-oxide was found to be an efficiently catalytic system for the N-arylation of imidazole, indole, benzimidazole, pyrrole, benzylamine and ethanolamine with aryl iodides and bromides by using NaOH as base in the presence of 20 mol% (n-Bu)4NBr, and water as solvent at 130 C in 24 h, and giving the N-arylated products in moderate to excellent yields.
