环戊二烯基二硫代氨基甲酸钛(Ⅳ), 锆(Ⅳ)配合物的合成及结构表征

(RCp)~2MCl~2, (RCp)TiCl~3分别与N-(4-苯基-2-噻唑基)二硫代氨基甲酸钾和3-苯基-5-(2-呋喃基)-吡唑啉-1-二硫代甲酸钠进行反应, 合成了三十二个未见报道的(RCp)M(S~2CNHR')~nCl~3~-~n,(RCp)~2M-(S~2CNHR')~nCl~2~-~n R=H, Me; M=Ti, Zr; R'=4-苯基噻唑基(PTDTC), n=1,2,3] 以及(RCp)M(S~2CR^2)~nCl~3~-~n,(RCp)~2M(S~2CR^2)~nCl~2~nR=H,Me;M=Ti,Zr,R^2=3-苯基-金-(呋喃-2)吡唑啉基(PFPDTC), n=1,2,3]型配合物。所有配合物经元素分析、UV、IR和^1H NMR谱证实, 二硫代氨基甲酸是以双齿配体键合的。

Synthesis and characterization of cyclopentadienyl titanium (Ⅳ) , zirconium(Ⅳ) dithiocabamato complexes

Thirty two new dithiocarbamate complexes of six, seven coordinated titanium (Ⅳ) or zirconium(Ⅳ) ] with the structures of (RCp)M(S~2CNHR^1)~nCl~3~-~n, (RCp)~2M(S~2CNHR^1)~n Cl~2~-~n R=H,Me; M=Ti, Zr; R^1=PTDTC,n=1,2,3] and (RCp)M (S~2CR^2)~n Cl~3~-~n, (RCp)~2M(S~2CR^2)~n Cl~2~-~n R=H, Me; M=Ti, Zr; R~2=PFPDTC, n=1,2,3] were prepared by the reaction of dichlorobis (cyclopentadienyl ) titanium (or zirconium); trichlorocyclopentadienyl titanium or trichloromethylcyclopentadienyl titanium with potassium 3-phenyl-thiazolyl dithiocarba mate or sodium 3-phenyl-5-(2-furanyl)-pyrazoline dithiocarbamate. All complexis were characterized by elemntal analysis, ^1H NMR, IR and UV spectra, which showed that dithiocarbamic acid coordinates as a bidentate ligand with metal.
