In 2019,Green Chemistry included an article by Lang, Xian-Dong; You, Fei; He, Xing; Yu, Yi-Chen; He, Liang-Nian. Quality Control of 1-Bromo-4-iodobenzene. The article was titled 《Rhodium(I)-catalyzed Pauson-Khand-type reaction using formic acid as a CO surrogate: an alternative approach for indirect CO2 utilization》. The information in the text is summarized as follows:
Formic acid was found to be an ideal CO surrogate for the rhodium(I)-catalyzed Pauson-Khand-type (PK-type) reaction of various substituted 1,6-enynes to afford bicyclic cyclopentenones I [R = Ph, 2-MeOC6H4, 4-BrC6H4, etc.] and II [R1 = Ph, 4-FC6H4 2-ClC6H4, etc.] in moderate to good yields. High TON value up to 263 and good results in the gram-scale experiment were also obtained. In addition, heterocyclic mols. of pharmaceutical importance were also furnished via inter- or intra-mol. hetero-PK-type reactions, further broadening the application of current strategy. Formic acid was utilized as a bridging mol. for the conversion of CO2 to CO, since formic acid was manufactured via catalytic hydrogenation of CO2 and released CO in the presence of acetic anhydride readily. Therefore, this methodol. represented a green and indirect approach for chem. valorization of CO2 in the preparation of value-added compounds In addition to this study using 1-Bromo-4-iodobenzene, there are many other studies that have used 1-Bromo-4-iodobenzene(cas: 589-87-7Quality Control of 1-Bromo-4-iodobenzene) was used in this study.
1-Bromo-4-iodobenzene(cas: 589-87-7) has been employed as reagent for in situ desilylation and coupling of silylated alkynes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids), as substrate in copper-free Sonogashira coupling in aqueous acetone in synthesis of β,β,dibromostyrenesQuality Control of 1-Bromo-4-iodobenzene
