Ikeda, Yuto; Inagaki, Yusuke; Setaka, Wataru published their research in Chemical Communications (Cambridge, United Kingdom) in 2021. The article was titled 《Simultaneous synthesis and characterization of in/out-isomers of disilabicyclo[14.14.14]alkanes》.Quality Control of Indium(III) bromide The article contains the following contents:
Facile and simultaneous synthesis of diphenyl-disilabicyclo[14.14.14]alkane in/out-isomers was achieved by using organosilicon chem. Although the formation of several in/out-isomers would be conceivable, only two diastereomers, i.e. the (traditional-)out,out-isomer and the twist-out,out-isomer, could be isolated because of homeomorphic isomerization. Crystal structures of the diastereomers were confirmed. In addition to this study using Indium(III) bromide, there are many other studies that have used Indium(III) bromide(cas: 13465-09-3Quality Control of Indium(III) bromide) was used in this study.
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.Quality Control of Indium(III) bromide
