The diastereoisomers resulting from the additional chiral sulfur center in the sulfoxides could be separated. Their configuration was assigned by NMR spectroscopy and in one case unequivocally corroborated by an X-ray structure analysis. The observed stereoselectivity of the oxidation can be attributed to the specific steric requirements in the different thietano sugars. X-Ray structural analyses of three crystalline sulfones were also performed. Attempts to generate carbanions of the sulfoxides and sulfones and to use these for reactions with electrophiles were not successful.","PeriodicalId":20043,"journal":{"name":"Phosphorus Sulfur and Silicon and The Related Elements","volume":"26 1","pages":"919 - 928"},"PeriodicalIF":0.0,"publicationDate":"2017-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83398696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This new plastic has been found to be an advantageous component of lithium-sulfur batteries and can be processed into lenses with a high refractive index and suitable for IR thermal imaging. These polymers are also shown to be “self-healing.” That is, scratched and now opaque lenses can be repaired simply by thermal treatment. Polymerization of sulfur with 1,4-diphenylbutadiyne provides stable polymers with thiophene sulfur linkages which are improved cathode materials for lithium-sulfur batteries. Studies delineating the chemistry behind these remarkable results and characterization of these materials has been explored.","PeriodicalId":20043,"journal":{"name":"Phosphorus Sulfur and Silicon and The Related Elements","volume":"3 1","pages":"157 - 161"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91047212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
