Amination of N-(Organodithio)phthalimides for the Modular Synthesis of Aminodisulfides

Synthetic methods for unsymmetrical aminodisulfides are greatly needed due to their applications in drug discovery, linker chemistry, and materials sciences. In this study, an amination reaction of N-dithiophthalimides has been developed for the divergent synthesis of unsymmetrical aminodisulfides. The reaction proceeds under mild conditions and provides the aminodisulfides in excellent yields without cleavage of the disulfide bond. The N-dithiophthalimides are readily available from several bilateral disulfurating reagents, and the broad substrate scope of this reaction allows for the modular synthesis of a variety of unsymmetrical aminodisulfides in two-step operations.

Easy to make highly efficient FG@ACC stable platform for sp3C-CF3 bond generation and NADH regeneration under sun light

The conversion of sun light energy into sustainble greener chemicals are a major obstacle due to the use of expensive and toxic materials. Sun light induced trifluoromethylation emerges as a highly efficient procedure to insert trifluoromethyl groups into the organic compounds. Yet, the expensive and toxic properties of the metal-based photocatalysts creates a major obstacle for the insertion of trifluoromethyl groups. Metal free activated carbon cloth (ACC) emerged as a highly efficient pillar in the area of material science. In this work, we have successfully synthesized self-assembled metal free fast green with activated carbon cloth (FG@ACC) photocatalyst for photocatalytic trifluoromethylation and reduced nicotinamide adenine dinucleotide (NADH) cofactor regeneration (85.89 %, 2 h) under sun light. The sun light induced organic transformation promotes the use of low-cost CF3SO2Na as the CF3 radical source to produce highly selective products with 97% yield.

Benzylic C(sp3)-H Bonds Play the Dual Role of Starting Material and Oxidation Inhibitor for Hydrazides in the Electrochemical Synthesis of Hydrazones

The electrooxidation of benzylic C(sp³)-H bonds to produce hydrazones as an alternate for conventional pathways has an enormous dignity. Under the aegis of electricity, instead of hazardous metal catalysts and external oxidants, we unveil an electrochemical process for electrooxidation of various benzylic C(sp³)-H bonds in aqueous media in all pH ranges that subsequently produce hydrazones with further reactions. This electrooxidative reaction strategy provides an acceptable condition for synthesizing hydrazones with various functional groups in good efficiency and amenable to gram-scale synthesis. The electrochemical oxidation condition proves an excellent level of compatibility with super cheap electrolyte NaCl for the oxidation of benzylic C(sp³)-H position despite the highly oxidizable hydrazide group remaining intact in the reaction.
