Arylation and alkylation of 6H-dibenzo[c,e][1,2λ5]oxaphosphinine 6-oxide at the phosphorus atom was accomplished. Tetrafluoro-4-pyridyl fragment was introduced via reaction of 6-trimethylsiloxy-6H-dibenzo[c,e][1,2]oxaphosphinine with pentafluoropyridine. The arylation of the title compound with aryl iodides containing both electron-acceptor and electron-donor substituents was effected under catalysis by palladium or nickel complexes.
在磷原子上成功实现了6H-二苯并[c,e][1,2λ5]氧磷烯-6-氧化物的芳基化和烷基化。通过将6-三甲基硅氧基-6H-二苯并[c,e][1,2]氧磷烯与五氟吡啶反应,引入了四氟-4-吡啶基片段。使用铂或镍络合物催化,成功进行了该化合物与包含电子受体和电子给体取代基的芳基碘化物的芳基化反应。
