Dialkyl Sulfides

Details are provided of synthetic routes from dialkyl sulfides to both α-halosulfoxides and sulfinyl chlorides. In the case of the former, oxidation of α-halosulfides to the sulfoxide stage is achieved by chlorine in acetic acid containing controlled amounts of water. Sulfinyl chlorides are prepared by chlorination of α-polyhalosulfoxides in methylene chloride. During investigations into the details of the sulfohaloform reaction, a number of novel redox reactions involving oxygen transfer between sulfur species have been observed and these are presented. They include a reduction of a sulfoxide with thionyl chloride.

Lithium–sulfur batteries with an ultrahigh theoretical energy density of 2600 Wh kg −1 are highly considered as desirable next-generation energy storage devices that will meet the growing demand of energy consumption worldwide. However, complicated sulfur redox reactions and polysulfide shuttling significantly postpone the applications of lithium–sulfur batteries with rapid capacity decay and low Coulombic efficiency. Herein, a unique strategy of polysulfide electrocatalysis is proposed to improve the kinetics of the sulfur species and inhibit polysulfide shuttling in working lithium–sulfur batteries. Inspired by a natural biocatalyst and congener oxygen electrocatalysis, porphyrin was selected as the electrocatalytic active site, and framework porphyrin (POF) electrocatalysts were rationally designed, precisely fabricated, and demonstrated superior full-scheme electrocatalytic performance with regard to improving the kinetics for polysulfide conversion, Li 2S nucleation, and dissolution of Li 2S to polysulfides, simultaneously. Consequently, the lithium–sulfur batteries with POF electrocatalysts achieve high capacity of 1611 mAh·g −1 at 0.1 C; outstanding stability with the capacity decay rate of 0.071% in 400 cycles, and satisfied performance with a high sulfur loading up to 4.3 mg·cm −2. The strategy of polysulfide electrocatalysis develops our chemical understanding of sulfur species in energy-related applications and inspires the electrocatalysis concept for extended energy conversion and storage systems based on multielectron redox reactions.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.
