Electric Literature of Br3InIn 2021 ,《Indium-Catalyzed Deoxygenation of Sulfoxides with Hydrosilanes》 was published in Asian Journal of Organic Chemistry. The article was written by Sakai, Norio; Shimada, Retsu; Ogiwara, Yohei. The article contains the following contents:
Described herein was that a novel InBr3/PhSiH3 reducing system in a 1,4-dioxane solution smoothly and effectively undertook deoxygenation of a variety of sulfoxides led to the facile preparation of sulfide derivatives R1SR2 [R1 = Ph, cyclohexyl, n-Bu, etc.; R2 = Ph, Me, Bn, etc.; R1R2 = (CH2)4]. Also, it was demonstrated that the reducing system showed a higher reactivity toward sulfoxides than that toward commonly reducible functional groups, such as carboxylic acids, esters, amides and sulfones. The experimental part of the paper was very detailed, including the reaction process of Indium(III) bromide(cas: 13465-09-3Electric Literature of Br3In)
Indium(III) bromide(cas: 13465-09-3) is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones.Electric Literature of Br3In
