Cyclometalated platinum(II) complexes (C-P)Pt(Aryl)py undergo oxidative addition reaction upon treatment with electrophilic fluorination reagents, XeF(2) or N-fluoro-2,4,6-trimethylpyridinium tetrafluoroborate, giving eventually products of C-C coupling. However, when aryl = mesityl, the two reagents give completely different products: the N-F salt still favors the C-C coupling reaction while XeF(2) gives the unprecedented benzylic fluorination of one of the ortho-methyl groups of the mesityl ligand.
环金属化铂(II)配合物 (C-P)Pt(芳基)py 在与亲电氟化试剂 XeF(2)或 N-氟-2,4,6-三甲基吡啶四氟硼酸盐反应时会发生氧化加成反应，最终生成 C-C 偶联产物。然而，当芳基 = 均三甲苯基时，这两种试剂会得到完全不同的产物：N-F 盐仍然有利于 C-C 偶联反应，而 XeF(2)则导致均三甲苯基配体的一个邻甲基发生前所未有的苄基氟化。
