highly reactive BrF3 as a precursor. Recently, we proposed chelation-stabilized hypervalent bromine(III) compounds as a possible solution to both problems. First, they can be conveniently prepared by electro-oxidation of the corresponding bromoarenes. Second, the chelation endows bromine(III) species with increased stability while retaining sufficient reactivity, comparable to that of iodine(III) counterparts

2-aryloxy-3-butenoic acid esters by allylic C–H bond carboxylation of allyl aryl ethers with CO2 has been achieved through deprotonative alumination with an aluminium ate compound (iBu3Al(TMP)Li) followed by NHC-copper-catalysed carboxylation of the resulting aryloxy allylaluminum species. Functional groups such as halogens (F, Cl, Br, I), CF3, amino, methylthio, silyloxy and hetero aromatic groups survived the
通过用铝酸酯化合物(i Bu 3 Al(TMP)Li)然后进行NHC的去质子化铝,通过烯丙基芳基醚与CO 2的烯丙基C–H键羧化烯丙基C–H键羧化,可以有效合成2-芳氧基-3-丁烯酸酯-铜催化的芳氧基烯丙基铝物种的羧化反应。诸如卤素(F,Cl,Br,I),CF 3,氨基,甲硫基,甲硅烷氧基和杂芳族基团的官能团在反应条件下幸存下来。2-芳氧基-3-丁烯酸酯产物的区域和立体选择性转化(异构化)为(Z在催化量的DBU存在下也已经获得了)-2-芳氧基-2-丁烯酸酯异构体。因此,这些转化构成了一种有效的方案,用于使用CO 2作为C1结构单元,从单一的烯丙基芳基醚底物发散合成2-芳氧基3-2和2-丁烯酸酯。
