本文报道了双(η~5-烷基环戊二烯基)水杨酸钼(IV)、钨(IV),双(η~5-环戊二烯基)双(α-呋喃甲酸)钼(IV)、钨(IV),双(η~5-环戊二烯基)双(取代苯甲酸)钼(IV)、钨(IV)等三十四个配合物的合成及性质.这些配合物能同氯化氢、乙酰氯、二氯亚砜反应生成相应的二茂金属二氯化物,与氯化亚锡反应生成含有Mo-Sn键的配合物.通过对双(η~5-环戊二烯基)双(取代苯甲酸)钼(IV)配合物的~(12)C NMR谱考察,发现羧羰基碳的~(13)C化学位移值与取代基场效应常数(σ_1)有一直线关系.
In this paper, the effects of molybdenum (IV), tungsten (IV), bis (5 ~ cyclopentadienyl) bis (α-furoic acid) (IV), Tungsten (IV), thirty-four complexes of bis (η~5-cyclopentadienyl) bis (substituted benzoate), molybdenum (IV) and tungsten (IV) The reactant can react with hydrogen chloride, acetyl chloride and thionyl chloride to form the corresponding metallocene dichloride and react with stannous chloride to form a complex containing Mo-Sn bond. The (12) C NMR spectra of the complexes of bis (substituted benzoic acid) and alkenyl () -bis (substituted benzoic acid) show that there is a linear relationship between the ~ (13) C chemical shift of carboxyl carbonyl carbon and the field effect constant (σ_1) .
