The reactions of dicyclopentadienylzirconium(IV) dichloride with picolinoyl, nicotinoyl and isonicotinoyl hydrazones derived from the appropriate acid hydrazides and acetone, acetophenone, salicylaldehyde or o-hydroxyacetophenone, have been studied in anhydrous tetrahydrofuran or dichloromethane in the presence or absence of amine using different molar ratios. Tentative structural coclusions are drawn
在无水四氢呋喃或二氯甲烷中,在存在或不存在胺的情况下,研究了无水四氢呋喃或二氯甲烷中二环戊二烯基二氯化锆(IV)与衍生自适当酸酰肼和丙酮,苯乙酮,水杨醛或邻羟基苯乙酮的吡啶甲酸,烟碱和异烟酰肼的反应。比率。根据元素分析,电导率,磁矩和光谱数据(电子,红外和1 H NMR)为反应产物绘制了暂定的结构共轭关系。这些配体表现为中性或去质子化的螯合剂。配位行为取决于介质的pH,取代基的性质以及hydr基相对于吡啶氮核的位置。
