对能够催化有机底物被氧或简单氧化剂氧化的物种的研究已经得到了本身在氧化反应条件下不可降解的催化剂物种的开发的帮助。在这方面，金属氧化物长期以来被认为是具有巨大价值的氧化催化剂。许多这些氧化物的可溶性类似物已经被创造出来，以帮助理解散装材料的反应性;通过控制合成可以获得与散装材料所表现出的性质不同的物质。我们的方法涉及制备，在一个受控的方式，表面结合的有机金属物种，我们现在报告的氧化两个这样的铑物种，可以在温和的条件下转化为分子氧或臭氧加合物使用O{sub 2}或O{sub 3}，分别。我们相信后一种化合物是第一个在环境条件下制备和稳定的臭氧复合物的例子。
The search for species capable of catalyzing oxidation of organic substrates by oxygen or by simple oxidizing reagents has been assisted by the development of catalyst species which are themselves nondegradable under oxidizing reaction conditions. In this regard, metal oxides have long been known as oxidation catalysts of tremendous value. Soluble analogues of many of these oxides have been created to help understand the reactivity of bulk materials; species with properties different from those exhibited by bulk materials may be obtained through controlled synthesis. Our approach involves preparing, in a controlled fashion, surface bound organometallic species, and we now report the oxidation of two such rhodium species which can be converted under mild conditions to dioxygen or ozone adducts using O{sub 2} or O{sub 3}, respectively. We believe the latter compound to be the first example of an ozone complex prepared and stable under ambient conditions.
