4-Acetamido-2,2,6,6-tetramethyl-1-oxopiperidinium tetrafluoroborate (Bobbitt's salt) effectively activates electron rich alkenes and promotes the addition of anilines. This transformation provides a direct, transition metal free method for amino-oxidation of alkenes under mild conditions. The relative stereochemistry of the amino-oxidation is influenced by solvent effects, with both the syn and anti
4-Acetamido-2,2,6,6-tetramethyl-1-oxopiperidinium 四氟硼酸盐(波比特盐)有效激活富电子烯烃并促进苯胺的添加。这种转变为烯烃在温和条件下的氨基氧化提供了一种直接的、无过渡金属的方法。氨基氧化的相对立体化学受溶剂效应的影响,顺式和抗氨基氧化产物都可以从相同的起始材料中获得。
