A straightforward and scalable approach to a previously unreported class of cyclic hypervalent Br(III) species capitalizes on the anodic oxidation of aryl bromide to dimeric benzbromoxole that serves as a versatile platform to access a range of structurally diverse Br(III) congeners such as acetoxy-, alkoxy-, and ethynyl-λ3-bromanes as well as diaryl-λ3-bromanes. The synthetic utility of dimeric λ3-bromane
一种直接和可扩展的方法来处理以前未报道的一类环状高价 Br(III) 物种,它利用芳基溴的阳极氧化生成二聚苯并溴索,作为一个多功能平台来获取一系列结构多样的 Br(III) 同系物,例如乙酰氧基-、烷氧基-和乙炔基-λ 3 -溴烷以及二芳基-λ 3 -溴烷。二聚 λ 3 -溴烷的合成效用通过光诱导的 Minisci 型杂芳基化反应和苄基氧化反应得到例证。
