Abstract

The organically modified titanium alkoxides Ti₂(Oi-Pr)₄(OOCCMe₂O)₂(i-PrOH)₂ and Ti₄(Oi-Pr)₄(SA)₆ were obtained from the reaction of Ti(Oi-Pr)₄ with 2-hydroxy-isobutyric acid and salicyladoxime (SA-H₂), respectively. Reaction of 1,3-dibenzoyl acetone (DBA-H) did not result in a substituted titanium alkoxide derivative, but instead in the oxo cluster Ti₄O₂(Oi-Pr)₈(DBA)₂ after allowing moisture to diffuse into the reaction mixture. The three titanium compounds show common structural features which are different to derivatives void of ligand OH groups. The latter play a decisive role in coordinating the ligands to the titanium centers.

具有羟基取代的双齿配体的烷氧基钛衍生物的结构化学

摘要

有机改性的烷氧基钛的Ti ₂（O异PR）₄（OOCCMe ₂ O）₂（I- PrOH中）₂和Ti ₄（O异PR）₄（SA）₆选自Ti的反应制得（O我- PR）₄与2-羟基异丁酸和salicyladoxime（SA-H ₂分别地）。1,3-二苯甲酰丙酮（DBA-H）的反应未生成取代的烷氧基钛衍生物，而是在氧簇Ti ₄ O ₂（O i- Pr）₈（DBA）中产生_2.让水分扩散到反应混合物中之后。三种钛化合物显示出共同的结构特征，这些特征不同于没有配体OH基团的衍生物。后者在配体与钛中心的配位中起决定性作用。
