The reaction of 5,6-dihydro-4H-1,2-oxazines, which are derived from α-bromooximes and enamines, with iron carbonyl complexes such as Fe3(CO)12 and (C2H5)3NH[HFe3(CO)11] gives pyrrole derivatives in high yields, accompaning deoxygenation from the oxazines. The pyrroles are also obtained by an one-pot reaction using α-bromooximes, enamines and iron carbonyls.
衍生自 α-溴肟和烯胺的 5,6-二氢-4H-1,2-恶嗪与铁羰基络合物如 Fe3(CO)12 和 (C2H5)3NH[HFe3(CO)11] 的反应以高产率得到吡咯衍生物,伴随着恶嗪的脱氧作用。吡咯也可通过使用 α-溴肟、烯胺和羰基铁的一锅反应获得。
