A synthetic cycle for aryl C-F substitution comprising oxidative addition, ligand metathesis, and reductive elimination at a Cs-sym. phosphorus triamide PN(2-MeNC6H4)2 (1) is reported. Reaction of 1 with perfluoroarenes (ArF-F) results in C-F oxidative addition, yielding fluorophosphoranes 1路[F][ArF]. The P-fluoro substituent is exchanged for hydride by treatment with DIBAL-H, generating hydridophosphoranes 1路[H][ArF]. Heating of 1路[H][ArF] regenerates 1 by C-H reductive elimination of ArF-H, where exptl. and computational studies establish a concerted but highly asynchronous mechanism. The results provide well-characterized examples of the full triad of elementary mechanistic aryl C-X substitution steps at a single main-group site. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Related Products of 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six 蟺 electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H眉ckel criteria for aromatic systems. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C鈥揌 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Related Products of 700-16-3
