1Synthetic[FeFe]-H_2ase models bearing phosphino thioether chelating ligands显示文摘A series of{2Fe3S}complexes bearing phosphino thioether chelating ligand were synthesized on the basis of Fe_2(Me_2pdt)(1,2-Cy_2PC_6H_4SMe)(CO)_4(Me_2pdt=Me_2C(CH_2S^1)_2,1).The disubstituted Fe(Ⅰ)Fe(Ⅰ)compound 1 exhibits a reversible one-electron redox even for[Fe(Ⅰ)Fe(Ⅱ)]^(+/0)couple.Based on the oxidation of 1 to[1]^+,the tri-substituted[Fe(Ⅰ)Fe(Ⅱ)]^+cationic complex[Fe_2(Me_2pdt)(1,2-Cy_2PC_6H_4SMe)(PPh_3)(CO)_3]^+([2]^+)was synthesized.Reduction of[2]^+provided the neutral tri-substituted Fe(Ⅰ)Fe(Ⅰ)compound 2.The substitution of the CO in 1 ligand by PPh_3results in an anodic shift of the Fe^(Ⅱ)Fe~Ⅰ/Fe_ⅠFe_(Ⅰ )couple of 470 mV.Most importantly,this substitution also leads to the Fe-Fe bonds in 1 and 2 with large Lewis basicity difference,i.e.DpK_a^(MeCN)$10.Yingjie Zhao Xin Yu Huilan Hu Xinlong Hu Sakthi Raje Raja Angamuthu Chen-Ho Tung Wenguang Wang 2018Chinese Chemical Letters2018,29,11:0
