通过适当的无水金属氯化物与六氟异丙醇钠的反应合成了铝、硅、锗、钛、锆和铪的共价氟取代异丙醇盐，可用作特定有机反应和各种聚合反应的催化剂。使用化学分析、红外光谱、质谱碎片数据、质子和氟核磁共振、热重分析和气相色谱来表征这些化合物。硅和钛的六氟异丙醇盐是液体，而铝、锗、锆和铪的六氟异丙醇盐是白色结晶固体。热分解和水解分解对氧化物进行定量。
Covalent, fluoro-substituted isopropoxides of aluminum, silicon, germanium, titanium, zirconium, and hafnium have been synthesized by the reaction of appropriate anhydrous metal chlorides with sodium hexafluoroisopropoxide for possible use as catalysts for specific organic and various polymerization reactions. Chemical analysis, infrared spectra, mass spectrometric fragmentation data, proton and fluorine nuclear magnetic resonance, thermal gravimetric analysis, and vapor-phase chromatography were used to characterize these compounds. The hexafluoroisopropoxides of silicon and titanium were liquid and those of aluminum, germanium, zirconium, and hafnium were white crystalline solids. Thermal and hydrolytic decomposition was quantitative to the oxides.
