腙类配位化合物的研究——Ⅰ.乙酰基一和1,1′—二乙酰基二茂铁苯甲酰腙及其过渡金属螯合物的制备和性质

COORDINATION COMPOUNDS OF HYDRAZONES——Ⅰ. PREPARATION AND PROPERTIES OF CHELATES OF ACETYL-AND 1,1'-DIACETYLFERROCENE AROYLHYDRAZONES WITH TRANSITION METALS

制备了两个二茂铁基芳酰基腙:乙酰基二茂铁苯甲酰腙,FcCMe=NNHCOC_6H_5(HL~Ⅰ)和1,1′--二乙酰基二茂铁苯甲酰腙,Fe(C_5H_4CMe=NNHCOC_6H_5)_2(H_2L~Ⅱ)。HL~Ⅰ和H_2L~Ⅱ与过渡金屑醋酸盐反应,得到两种螯合物:ML_2~Ⅰ和ML~Ⅱ[M=Co(Ⅱ)、Zn(Ⅱ)和Cd(Ⅱ)]。对这些螯合物的元素分析,差热热重分析、IR、UV及~1HNMR谱进行了详细讨论。

Two ferrocenyl aroyl hydrazones: acetylferrocene benzoylhydrazone, FcCMe = NNHCOPh(HL Ⅰ ); 1,1'-diacetylferrocene benzoylhydrazone, Fe(C5H4CMe = NNHCOPh)2(H2LⅡ)and their chelates with M(OAc)2·nH2O(M = Co, Zn and Cd) have been prepared. The elemental analysis, IR, UV, PMR and TG-DTA are discussed in detail and showed that these ligands are coordinated in the enolic form with transition metal acetates.
