In 2019,Chinese Journal of Chemistry included an article by Zhu, Bo-Han; Wang, Cai-Ming; Su, Hong-Yu; Ye, Long-Wu. Reference of 1-Bromo-4-iodobenzene. The article was titled 《NaBArF4-Catalyzed Oxidative Cyclization of 1,5- and 1,6-Diynes: Efficient and Divergent Synthesis of Functionalized γ- and δ-Lactams》. The information in the text is summarized as follows:
An efficient NaBArF4-catalyzed oxidative cyclization of readily available 1,5- and 1,6-diynes was developed. Importantly, this transition metal-free oxidative catalysis proceeded via a presumable Lewis acid-catalyzed SN2′ pathway, which was distinct from the relevant oxidative rhodium and gold catalysis. This method lead to the facile and practical construction of a diverse range of synthetically useful γ- and δ-lactams in mostly good to excellent yields with broad substrate scope. In the experiment, the researchers used 1-Bromo-4-iodobenzene(cas: 589-87-7Reference of 1-Bromo-4-iodobenzene)
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,dibromostyrenesReference of 1-Bromo-4-iodobenzene
