In 2022,Konishi, Hideyuki; Fujita, Ririka; Yamaguchi, Miyuki; Manabe, Kei published an article in Organic Letters. The title of the article was 《Synthesis of Symmetrical Sulfides Enabled by a Sulfur Dioxide Surrogate Acting as a Divalent Sulfur Source》.Electric Literature of C9H11Br The author mentioned the following in the article:
A safe and practical methodol. for synthesizing sym. sulfides using iodoarenes and potassium metabisulfite (K2S2O5) was presented. While K2S2O5 was known as a convenient sulfur dioxide surrogate, here it acted as a divalent sulfur source, pioneering its potential utility. The reaction exhibited wide substrate generality in which even highly bulky substrates can be applied to afford sterically congested sulfides. The experimental part of the paper was very detailed, including the reaction process of 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Electric Literature of C9H11Br)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Electric Literature of C9H11Br The most pervasive is the naturally produced bromomethane.
