Sun, Xu; Guo, Xiao-Qiang; Chen, Lian-Mei; Kang, Tai-Ran published their research in Chemistry – A European Journal in 2021. The article was titled 《Synthesis, Characterization of Spirocyclic λ3-Iodanes and Their Application to Prepare 4,1-Benzoxazepine-2,5-diones and 1,3-Diynes》.Related Products of 625-99-0 The article contains the following contents:
Herein, a [3+2] cycloaddition of aza-oxyallylic cations I [R = H, 6-Cl, 5-NO2, 5-F; R1 = 2-bromophenyl, 4-(ethoxycarbonyl)benzen-1-yl, tris(propan-2-yl)silyl, etc.] with ethynylbenziodoxolones R2ONHC(O)C(CH3)2Br [R2 = allyl, i-Pr, Bn, (2,4-dichlorophenyl)methyl, etc.] for synthesis of new λ3-iodanes containing spirocyclic 4-oxazolidinone II is described. This cyclic λ3-iodanes II display stability in air and excellent solubility in organic solvent. Using the above compounds as substrate II, both the 4,1-benzoxazepine-2,5-diones III [R3 = Me, allyl, (2,4-dichlorophenyl)methyl, etc.; R4 = H, 7-Me, 8-Cl, 7-CF3] and sym. 1,3-diynes derivatives R5CCCCR5 [R5 = Ph, 2-bromophenyl, 1-naphthyl, etc.] were afforded in high yield under copper(I)-catalyzed conditions. After reading the article, we found that the author used 1-Chloro-3-iodobenzene(cas: 625-99-0Related Products of 625-99-0)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.Related Products of 625-99-0
