Metal or semimetal alkoxides substituted with nonhydrolyzable organic groups are important precursors for inorganic-organic hybrid materials. Understanding the chemistry and structural issues of such precursors is a prerequisite for a rational materials design. Examples are given in this Account, mainly from the chemistry of titanium and zirconium alkoxides, which show that modified metal alkoxide precursors sometimes have an unexpected and unpredictable stuctural chemistry. Furthermore, chemical consequences of the Lewis acidity of the metal alkoxides are discussed, such as adduct formation, ligand exchange reactions, or organic side reactions.
被不可水解有机基团取代的金属或半金属醇盐是无机-有机杂化材料的重要前驱体。了解此类前驱体的化学性质和结构问题是合理进行材料设计的前提。本综述给出了一些例子，主要来自钛和锆醇盐的化学领域，这些例子表明，改性金属醇盐前驱体有时具有意想不到且不可预测的结构化学性质。此外，还讨论了金属醇盐路易斯酸性的化学影响，如加合物形成、配体交换反应或有机副反应。
