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

Synthesis and Characterization of Cyclopentadienyl Titanium(IV)、 Zirconium(IV) Dithiocabamato Complexes

(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-呋哺基)-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-n)[R=H,Me;M=Ti,Zr,R^2=3-苯基-15-(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'H NMR谱证实,二硫代氨基甲酸是以双齿配体键合的。

Thirty two new dithiocarbamate complexes of six, seven coordinated titanium(IV) [ or zirconium (IV )] with the structures of (RCp)M(S2CNHR1)nCl3-n, (RCp)2M(S2CNHR1)n Cl2-n[ R=H, Me; M=Ti, Zr;R1= (PTDTC), n = 1, 2, 3] and (RCp)M(S2CR2)n Cl3-n, (RCp)2M(S2CR2)nCl2-n [R = H, Me; M=Ti, Zr; R2 = (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 Complexes were characterized by elemental analysis, 1H NMR, IR and UV spectra, which showed that dithiocarbamic acid Coordinates as a bidentate ligand with metal.
