dinuclear iron carbonylcomplexes. One of the iron atoms is bonded symmetrically to both exocyclic imine nitrogen atoms. The second iron atom shows a side-on coordination towards the CN bond next to the oxadiazine oxygen atom. In addition, the iron atoms are connected via a metal metal bond. The same oxadiazine derivatives produce chiral spiro-lactams in a ruthenium catalyzed formal [2+2+1] cycloaddition
N,N '-(4-甲基-4 H -1,3,4-恶二嗪-5,6-二亚甲基)-双苯胺衍生物与Fe 2(CO)9反应,生成羰基双核铁配合物。铁原子之一对称于两个环亚胺氮原子。第二个铁原子在恶二嗪氧原子旁边显示出对C N键的侧向配位。另外,铁原子通过金属-金属键连接。相同的恶二嗪衍生物在钌催化的一氧化碳和乙烯催化的正式[2 + 2 + 1]环加成反应中产生手性螺内酰胺。
