Branched allylic CF3 products are accessible by copper‐catalyzed trifluoromethylation of allylsilanes with the Togni reagent I. The silyl group is critical to control the outcome of this reaction because in its absence, a product of addition between the alkene and the Togni reagent is formed preferentially. The reaction is inhibited with 2,2,6,6‐tetramethyl‐1‐piperidinyloxy (TEMPO) and is likely to
支链烯丙基CF 3 产物可通过用Togni试剂I通过铜催化的烯丙基硅烷的三氟甲基化来获得。甲硅烷基对于控制该反应的结果至关重要,因为在不存在甲硅烷基的情况下,优先形成烯烃与Togni试剂之间的加成产物。该反应受2,2,6,6-四甲基-1-哌啶基氧基(TEMPO)的抑制,并且可能通过多种反应途径进行。
