Three isoskeletal tetranuclear coordination clusters with general formula M(II) 2 Dy(III) 2 L4 (EtOH)6 2 ⋅2 EtOH, (M=Co, 1; M=Ni, 2) and [Ni(II) 2 Dy(III) 2 L4 Cl2 (CH3 CN)2 ]⋅2 CH3 CN (3), have been synthesized and characterized. These air-stable compounds, and in particular 3, display efficient homogeneous catalytic behavior in the room-temperature synthesis of trans-4,5-diaminocyclopent-2-enones from 2-furaldehyde and primary or secondary amines under a non-inert atmosphere.
已合成并表征了三种具有通式M(II)₂Dy(III)₂L₄(EtOH)₆₂·2EtOH(M = Co,1;M = Ni,2)和[Ni(II)₂Dy(III)₂L₄Cl₂(CH₃CN)₂]·2CH₃CN(3)的等骨架四核配位簇。这些对空气稳定的化合物,特别是3,在非惰性气氛下由2-呋喃甲醛与伯胺或仲胺室温合成反式-4,5-二氨基环戊-2-烯酮的反应中表现出高效的均相催化行为。
