Dormant boron awaits its true destiny in diaryliodonium salts synthesized from aryl boronate derivatives according to two alternative general methods with hypervalent iodine(III) reagents and fluoroalcohol solvents: transformation of an aryl CH bond and boron–iodine(III) exchange (see scheme; FG=functional group). The salts could be functionalized by both catalyst‐free and metal‐catalyzed reactions
休眠硼正等待由芳基硼酸酯衍生物合成的二芳基碘鎓盐的真实命运,这是根据两种替代的通用方法,使用高价碘(III)试剂和氟代醇溶剂:芳基CH键的转化和硼-碘(III)的交换(参见方案) ; FG =官能团)。可以通过无催化剂和金属催化的反应来使盐官能化,而不会丧失硼的官能度。
