The intramolecular cyclocarbonylation of substituted 2-(2-iodophenoxy)anilines was catalyzed by PdI(2) 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.
取代的 2-(2-碘苯氧基)苯胺的分子内环羰化反应在 PdI(2)和 1,3,5,7-四甲基-6-苯基-2,4,8-三氧杂-6-磷杂金刚烷(Cytop 292)的催化下高效进行。在温和的反应条件下,以良好的产率制备了一系列取代的二苯并[b,f][1,4]恶嗪并-11(10H)-酮。
