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.

This work reports the synthesis and antibacterial activity of novel hydrazone derivatives 8a-k bearing 4-[3-methyl-4-(methylsulfonyl)pyridin- 2-yl] moiety. Spectroscopic techniques like 1H NMR, mass and IR tools was utilized for the characterization of these hydrazone derivatives. The synthesized hydrazone derivatives were tested against a set of bacterial strains, namely, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pyogenes by paper disc diffusion method. Compounds 8b, 8d, 8e, 8f, 8h, 8i showed good antibacterial activity against the test organisms.

Quinoxalines have been found to exhibit various biological activities such as antibacterial, antifungal, anti-tubercular, anxiolytic, anticancer, antioxidant, anti-inflammatory, anti-HIV, antihelmintic and anticonvulsant. The present study aims towards synthesis, characterization and determination of antimicrobial susceptibility testing of various novel quinoxaline derivatives. The quinoxaline-benzohydrazides 6a-m have been obtained by the condensation of quinoxaline-2-carboxaldehyde 4 with various benzohydrazides 5a-m in ethanol at reflux temperature. All the newly synthesized quinoxaline-benzohydrazide derivatives have been characterized by 1H NMR, IR and mass spectroscopic analysis. The synthesized quinoxaline-benzohydrazides 6a-m have been screened for antibacterial activity. Most of the compounds show significant antibacterial activity.
