In order to study the effect of steric bulk on the vanadium coordination geometry in O,N-chelated vanadium oxo (bis)phenol- ates, six different ortho-aminophenolate ligands have been used. The ortho-aminophenolate system was changed at three different places, i.e. 1) the second ortho position (C 6 ) of the arene ring (R), 2) the substituents at the amino nitrogen (R and R), and 3) the benzylic carbon
为了研究空间体积对 O,N 螯合的氧代(双)酚酸钒中钒配位几何结构的影响,使用了六种不同的邻氨基酚盐配体。邻氨基苯酚盐体系在三个不同的位置发生了变化,即 1) 芳烃环 (R) 的第二个邻位 (C 6 ),2) 氨基氮上的取代基 (R 和 R),以及 3) 苄基碳原子 (R * )。酚类用于制备氧代(双)酚钒络合物。为了研究是否可以预测几何特征
