2-Iodoaniline derivatives were used as bifunctional substrates in palladium-catalysed carbonylation. Depending on the substituents, two types of compounds were synthesised: having methyl or hydrogen in 4-position 2-aryl-benzo[d][1,3]oxazin-4-one derivatives have been formed, chloro, bromo, cyano or nitro groups in the same position resulted in the formation of dibenzo[b,f][1,5]-diazocine-6,12-dione
2-碘苯胺衍生物在钯催化的羰基化反应中用作双功能底物。取决于取代基,合成了两种类型的化合物:在4-位2-芳基-苯并[ d ] [1,3]恶嗪-4-酮衍生物中具有甲基或氢原子,氯,溴,氰基或硝基基团在相同位置导致形成二苯并[ b,f ] [1,5]-重氮电影-6,12-二酮衍生物。在各种伯胺和仲胺(叔丁胺,氨基酸甲酯)的存在下,以N-亲核试剂的形式获得了2-酮甲酰胺,这是氨基羰基化反应中一氧化碳双插入的主要产物。
