In 2018,Alonso-Maranon, Lorena; Sarandeses, Luis A.; Martinez, M. Montserrat; Perez Sestelo, Jose published 《Synthesis of fused chromenes by the indium(III)-catalyzed cascade hydroarylation/cycloisomerization reactions of polyyne-type aryl propargyl ethers》.Organic Chemistry Frontiers published the findings.Product Details of 13465-09-3 The information in the text is summarized as follows:
Fused 2H-chromenes were prepared by the cascade hydroarylation/cycloisomerization reactions of polyyne-type aryl propargyl ethers using indium(III) catalysis. The transformation proceeded with 6-endo-dig regioselectivity using InBr3 (5 mol%). The method was extended to triynes allowing the formation of three bonds in one pot. Indium(III) also catalyzed the hydroamination/hydroarylation cascade reaction of o-aryldiynyl anilines to form fused carbazoles. In the experimental materials used by the author, we found Indium(III) bromide(cas: 13465-09-3Product Details of 13465-09-3)
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.Product Details of 13465-09-3
