Abstract A series of half-sandwich type complexes with [(C5R5)Co(L)] (R = H, Me; L = PR3, P(OR)3, CNR), [(C5R5)Rh PR 3 ′ ] (R = H, Me) and [(C5H5)Ir(PiPr3)] as building blocks and trithiocarbonate, dithiocarbonate, N-cyanodithiocarbimate, 1,1-dicyanoethylene-2,2-dithiolate and 1,1-dicyanoethylene-2,2-diselenolate as chelating ligands was prepared. They were characterized by mass spectrometry and IR
摘要一系列具有[(C5R5)Co(L)](R = H,Me; L = PR3,P(OR)3,CNR),[(C5R5)Rh PR 3'](R = H,Me)和[(C5H5)Ir(PiPr3)]作为构建基块,并包含三硫代碳酸酯,二硫代碳酸酯,N-氰基二硫代氨基甲酸酯,1,1-二氰基乙烯-2,2-二硫代酸酯和1,1-二氰基乙烯-2,2-二硒代酸酯制备螯合配体。它们通过质谱,IR,UV和NMR光谱技术进行了表征。将三硫代碳酸酯衍生物[(C5R5)Co(PMe3)(S2C S)](R = H,Me)用[Fe(C5H5)2] X(X = BF4,PF6)氧化为阳离子化合物[(C5R5)Co (PMe3)(S2C S)] X。半三明治型配合物的氧化电位通过循环伏安法测定。[(C5Me5)Co(PMe3)(S2C S)]与四氰基乙烯(TCNE)的反应导致配体片段交换,并生成1,1-二氰基乙烯-2钴,
