一些双(η~5-环戊二烯基)芳香酸钼(Ⅳ)、钨(Ⅳ)配合物的合成和性质研究
Syntheses and Properties of Some Bis(η~5-cyclopentadienyl) molybdenum(Ⅳ) and Tungsten(Ⅳ) Aromatic Acid Complexes
【摘要】 本文报道了双(η5-烷基环戊二烯基)水杨酸钼(IV)、钨(IV),双(η5-环戊二烯基)双(α-呋喃甲酸)钼(IV)、钨(IV),双(η5-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(η5-环戊二烯基)双(取代苯甲酸)钼(IV)配合物的12C NMR谱考察,发现羧羰基碳的13C化学位移值与取代基场效应常数(σ1)有一直线关系.
【Abstract】 The syntheses and properties of 34 bis (η5-alkylcyclopentadienyl)molybdenum (Ⅳ) and tungsten(Ⅳ) salicylate, bis (η5-cyclopentadienyl)molybdenum(Ⅳ) and tungsten(Ⅳ) dipyromucate, bis (η5-cyclopentadienyl) molybdenum (Ⅳ) and tungsten (Ⅳ) benzoates complexes are reported. These complexes react with hydrogen chloride, acetyl chloride and thionyl chloride to form the parent dichloride (η5-RC5H4)2 MCl2. and with stannous chloride to form Mo—Sn bonding complexes. The 13C NMR spectra of the complexes (η5-C5H5)2Mo(O2CC6H4Y)2(Y is substituent)showed that there is a linear relationship between the chemical shift of the carbonyl carbon and σ1 of the substituents.
