Method for synthesizing aryl alkyl sulfone compound by promoting oxidation of aryl alkyl thioether compound through visible light

The invention discloses a method for synthesizing an aryl alkyl sulfone compound by promoting oxidation of an aryl alkyl thioether compound through visible light. The method comprises the following steps of: performing one-pot reaction on an aryl alkyl thioether compound and sodium trifluoromethanesulfinate in a diethylene glycol dibutyl ether solution system under the conditions of oxygen-containing atmosphere and 385-390 nm purple light irradiation to generate the aryl alkyl sulfone compound. The method has the advantages of mild conditions, simple operation, environmental protection, easilyavailable raw materials, excellent compatibility of substrate functional groups, high reaction yield and the like.

Room Temperature Carbonylation of (Hetero) Aryl Pentafluorobenzenesulfonates and Triflates using Palladium-Cobalt Bimetallic Catalyst: Dual Role of Cobalt Carbonyl

An efficient method for the carbonylation of (hetero) aryl pentafluorobenzenesulfonates and triflates under exceptionally mild conditions using palladium/dicobalt octacarbonyl [Pd/Co2(CO)8] has been developed. Besides acting as carbon monoxide (CO) source, Co2(CO)8enhances the reaction rate by accelerating the CO insertion through an in situ generated bimetallic palladium cobalt tetracarbonyl [Pd-Co(CO)4] complex. Under the optimized reaction condition, carbonylation of a wide range of activated and deactivated, as well as sterically hindered and heteroaromatic, substrates proceeded efficiently at room temperature. The high chemoselectivity and improved synthesis of biologically relevant Isoguvacine and Lazabemide intermediates highlights its scope as a valuable synthetic method. The generality of this protocol was further extended to other electrophiles (bromides, chlorides and tosylates). (Figure presented.).

Synthesis and antimicrobial activity of new imidazole-hydrazone derivatives

Hydrazones demonstrated significant antimicrobial activity, antitubercular activity and antitumoral activity in medicinal areas. The imidazole nucleus is well known to play an important role in living organisms since it is incorporated into the histidine molecule and many other important biological, pharmacological and therapeutic activities. Condensation of 4-phenyl-1H-imidazole-2-carbaldehyde (3) with various selected benzohydrazides (4a-m) resulted in imidazole-hydrazone derivatives (5a-m). They were evaluated for antibacterial and antifungal activity against A. Niger, C. albicans (fungal strains), E. coli and P. aeruginosa (Gram-negative bacteria), S. aureus and S. pyogenes (Gram-positive bacteria) using griseofluvin (for fungi) and ciprofloxacin (for bacteria) as the standard drugs. In general, it is observed that most of the compounds were found to be potent against both the bacterial and fungal strains.

Correlation pKa - activitee catalitique des thiols dans la reeaction d'hydrolyse de l'aceetate de p-nitropheenyle

The kinetic study of the hydrolysis of p-nitrophenylacetate in the presence of primary thiols indicates the thiolate anion as the sole catalytic species.Comparison of the true second order constants (kRS-) reveals that purely aliphatic primary thiols behave differently from aromatic α-substituted primary thiols.In the latter group a correlation can be established between the true second order rate constants and the pKSH values by means of the Broensted equation log kRS- = βpKSH + C, with β equal to 0.40 and C equal to -0.85.
