substituted 2-(2-iodophenoxy)anilines was catalyzed by PdI2 and 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phospha-adamantane (Cytop 292) in an efficient manner. A series of substituted dibenzo[b,f][1,4]oxazepin-11(10H)-ones were prepared in good yields under mild reaction conditions.
PdI 2和1,3,5,7-四甲基-6-苯基-2,4,8-三氧杂-6-磷酸金刚烷(Cytop 292)催化取代的2-(2-碘苯氧基)苯胺的分子内环羰基化反应以有效的方式。在温和的反应条件下,以良好的收率制备了一系列取代的二苯并[ b,f ] [1,4]草酰ze11(10 H)-酮。
