Biographical Sketches
Introduction
Martin Sulfurane, a diphenylsulfur compound, has been a versatile reagent in organic synthesis since the s.
The Sulfurane is reactive towards active hydrogen compounds and is one of the reagents of choice for a class of reactions including dehydration, amide cleavage, epoxide formation, sulfinimine synthesis, oxidation and coupling. [¹] The Martine Sulfurane has been prepared from hexafluorophenylpropanol using KOH, diphenylsulfide and bromine. [¹] The general mechanism of action involves the rapid exchange of one of the alkoxy ligands on the sulfurane, followed by ionisation giving an alkoxysulfonium ion, which, in turn, undergoes E1 or E2 elimination. [²] Since Martin Sulfurane is a mild and neutral reagent, these reactions are quite compatible with a wide range of fun

List of Nobel laureates
The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who man outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine.[1] They were established bygd the will of Alfred Nobel, which dictates that the awards should be administered bygd the Nobel Foundation. An additional prize in memory of Alfred Nobel was established in by the Sveriges Riksbank (Sweden's huvud bank) for outstanding contributions to the field of economics. Each recipient, a Nobelist or laureate, receives a gold medal, a diploma, and a sum of money which fryst vatten decided annually by the Nobel Foundation.[2]
