In 2022,Echemendia, Radell; De Jesus, Matheus P.; Furniel, Lucas G.; Day, David Philip; Burtoloso, Antonio C. B. published an article in European Journal of Organic Chemistry. The title of the article was 《Molecular Iodine Mediated Oxidation of Arylated α-Carbonyl Sulfoxonium Ylides to 1,2-Dicarbonyl-Containing Compounds》.Category: bromides-buliding-blocks The author mentioned the following in the article:
In this work, a new oxidative, mol. iodine-mediated transformation on sterically encumbered arylated sulfoxonium ylides, which give access to 1,2-dicarbonyl containing compounds was reported. Twenty-six examples were realized (47-92% yields), with structural diversity modified at two key sites on the sulfoxonium ylide reactants. Furthermore, the protocol benefits from the use of inexpensive mol. iodine to mediate the oxidation and, from a sustainability viewpoint, short reaction times (30 min), ambient temperature, and Et acetate as a greener reaction solvent. Exptl. studies also gave insight to the mechanism of the reaction, involving DMSO as an oxygen source. The results came from multiple reactions, including the reaction of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4Category: bromides-buliding-blocks)
Furthermore, the coupling of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4) with β-methallyl alcohol was catalyzed by Pd(OAc)2 in combination with P(t-Bu)3.Category: bromides-buliding-blocks
