A fluoroform‐derived borazine CF3− transfer reagent is used to effect rapid nucleophilic reactions in the absence of additives, within minutes at 25 °C. Inorganic electrophiles spanning seven groups of the periodic table can be trifluoromethylated in high yield, including transition metals used for catalytic trifluoromethylation. Organic electrophiles included (hetero)arenes, enabling C−H and C−X
甲三氟甲烷衍生的环硼氮烷CF 3 -转移试剂在25用来快速作用的亲核反应在不存在添加剂时,在几分钟内℃。可以高产率地将跨越周期表的七个基团的无机亲电试剂三氟甲基化,包括用于催化三氟甲基化的过渡金属。有机亲电试剂包括(杂)芳烃,可实现CH和CX三氟甲基化反应。机理分析支持CF解离机构3 -转移,和阳离子改性,得到具有增强的稳定性的试剂。
