The cationic complex [Fe(P2S2)(NCMe)2]2+ (P2S2=(Ph2PC6H4CH2S)2(C2H4) ([1(NCMe)2]2+)), with two MeCN ligands in a cis orientation, was synthesized and characterized. The MeCN ligand in [1(NCMe)2]2+ undergoes further substitution by a hydride ligand or CO to give iron(II) hydrides [H1(NCMe)]+, [H1H]0, and [H1(CO)]+. The order of reactivity of the hydrides was [H1H]0>[H1(NCMe)]+>[H1(CO)]+, and was illustrated
阳离子络合物[Fe(P 2 S 2)(NCMe)2 ] 2+(P 2 S 2 =(Ph 2 PC 6 H 4 CH 2 S)2(C 2 H 4)([ 1(NCMe)2 ]合成并表征了具有两个顺式取向的MeCN配体的2+))。[ 1(NCMe)2 ] 2+中的MeCN配体被氢化物配体或CO进一步取代,得到氢化铁(II)[H 1(NCMe)]+,[H 1 H] 0和[H 1(CO)] +。氢化物的反应顺序为[H 1 H] 0 > [H 1(NCMe)] + > [H 1(CO)] +,并通过它们与质子酸(10-甲基ac的有机阳离子)的反应来说明。 (MeAcr +)作为氢化物受体,以及这些亚铁化合物之间的分子间氢化物转移反应。例如,MeAcr +最初通过[H 1 H] 0的单电子转移过程被还原,导致MeAcr竞争反应。二聚化,氢原子从[H 1 H] +转移到MeAcr 。以及[H 1 H] +
