A facile and efficient thiol-free one-pot method for direct synthesis of sulfides sulfoxides under green conditions without using any metal catalyst is reported. For this purpose, we used benzyl bromides as starting materials in the presence potassium thioacetate (PTA) Oxone® which are low-cost, readily accessible chemicals. This highly compatible with a variety functional groups delivered series sulfides, bis-sulfides, good yields. The selective formation over sulfones discussed via mechanism.

Compared with general redox chemistry, electrochemistry using the electron as a potent, controllable, yet traceless alternative to chemical oxidants/reductants usually offers more sustainable options for achieving selective organic synthesis. With its environmentally benign features gradually being uncovered and studied, electrosynthesis is currently undergoing revival becoming rapidly growing area within synthetic community. Among electrochemical transformations, anodically enabled ones have been far extensively exploited than those driven by cathodic reduction, although both approaches are conceptually attractive. To stimulate development of cathodically reactions, this review summarizes recently developed reductive electrosynthetic protocols, discussing highlighting reaction features, substrate scopes, applications, plausible mechanisms reveal recent trends in area. Herein, reduction-enabled preparative transformations categorized into four types: reduction (1) unsaturated hydrocarbons, (2) heteroatom-containing carbon-based systems, (3) saturated C-hetero or C–C polar/strained bonds, (4) hetero-hetero linkages. Apart from net electroreductive few examples photo-electrosynthesis well paired electrolysis also introduced, which offer opportunities overcome certain limitations improve versatility. The electrochemically driven, transition metal-catalyzed cross-couplings that comprehensively discussed several other reviews not included here.

Chlorine (Cl)-based batteries such as Li/Cl2 are recognized promising candidates for energy storage with low cost and high performance. However, the current use of Li metal anodes in Cl-based has raised serious concerns regarding safety, cost, production complexity. More importantly, well-documented parasitic reactions between electrolytes require a large excess metal, which inevitably sacrifices electrochemical performance full cell. Therefore, it is crucial but challenging to establish new anode chemistry, particularly reversibility, batteries. Here we show, first time, reversible Si redox through efficient electrolyte dilution anode/electrolyte interface passivation using 1,2-dichloroethane cyclized polyacrylonitrile key mediators. Our chemistry enables significantly increased cycling stability shelf lives compared conventional anodes. It also avoids materials, thus enabling rechargeable Cl2 battery remarkable power densities 809 Wh kg-1 4,277 W , respectively. The affords fast kinetics rate capability low-temperature performance, indicating its great potential practical applications.
