二氯二茂钛中两个氯原子与钛以不稳定的6—键结合,它们易被其它阴离子配位基取代和发生亲核反应,如二氯二茂钛可与醇、酚和酸反应生成相应的烃氧基或酰氧基化合物,这类化合物中当 Ti—O 键的氧原子与具有π—键的基团相连时,由于氧上未共用电子对与碳原子上π—电子发生共轭,使其较为稳定,所以近年来合成了一系列二茂钛芳氧基化合物,不存在这种共轭时,稳定性差,这方面的研究也较少本文由二氯二茂钛出发合成了三种未见文献报导的烃氧基和酰氧基二茂钛化合物:
Two chlorine dichloride titanyl and titanium with unstable 6-bond, they are easily replaced by other anionic ligand and nucleophilic reaction, such as dichloro titanocene with alcohol, phenol and acid reaction generated Corresponding hydrocarbyloxy or acyloxy compounds, in these compounds, when the oxygen atom of the Ti-O bond is connected to the group having a π-bond, since the unshared electron pair on the oxygen and the π-electron on the carbon atom Yoke, so that it is more stable, so in recent years a series of synthesis of titanocene aryloxy compounds, in the absence of such conjugates, the stability is poor, the research is also less In this paper starting from dichloro titanocene synthesis Three unreported hydrocarbyloxy and acyloxytitanocene compounds:
