COA of Formula: Br3InIn 2020 ,《A radical-mediated 1,3,4-trifunctionalization cascade of 1,3-enynes with sulfinates and tert-butyl nitrite: facile access to sulfonyl isoxazoles》 was published in Chemical Communications (Cambridge, United Kingdom). The article was written by Yue, Xin; Hu, Ming; He, Xingyi; Wu, Shuang; Li, Jin-Heng. The article contains the following contents:
An unprecedented indium-promoted three-component 1,3,4-trifunctionalization cascade of 1,3-enynes with sodium sulfinates and tert-Bu nitrite (TBN) to access 5-sulfonylisoxazoles I [R1 = Ph, 3-thienyl, CH2OCOPh, etc.; R2 = H, Me; R3 = Me, cyclopropyl, Ph, etc.] via [3+2] annulation was reported. By employing TBN as both the radical initiator and the N-O two atom unit, this method enabled the formation of three new carbon-heteroatom bonds, C-S, C-N and C-O bonds, in a single reaction through a sequence of sulfonylation, isomerization, nitration and annulation with a broad substrate scope, excellent selectivity and the potential of late-stage functionalization of natural products. The experimental process involved the reaction of Indium(III) bromide(cas: 13465-09-3COA of Formula: Br3In)
Indium(III) bromide(cas: 13465-09-3) is used as a catalyst to produce dithioacetals when unactivated alkynes react with thiols and fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium in high-performing solar cells.COA of Formula: Br3In
