使用F+源阵列实现了(三磷酸)Pt-R+的高产氟化,XeF2在几分钟内产生R-F。C-F耦合被证明是一个立体保持过程,通过从假定的指示Pt(IV)中心协同还原消除进行。(三磷酸)Pt-Csp3 +配合物的空间堵塞越大,氟化效率越高,这似乎是由于空间加速了C-F的还原消除,同时也减慢了其竞争过程(β-H消除)。
A high-yielding fluorination of (triphos)Pt-R+ has been achieved using an array of F+ sources, with XeF2 yielding R–F in minutes. The C–F coupling proved to be a stereoretentive process that proceeds via a concerted reductive elimination from a putative dicationic Pt(IV) center. The larger the steric congestion of the (triphos)Pt–Csp3+ complexes, the more efficient the fluorination, seemingly a result of sterically accelerated C–F reductive elimination along with simultaneous deceleration of its competing processes (β-H elimination).
