在绿色化学的指导思想下，介绍了醇类催化氧化的三种方法。第一种采用可回收的低聚克里思催化剂（PIPO）和次氯酸钠作为氧化剂在无溴化物和氯化烃溶剂的系统。第二种涉及钌/克里思催化剂和作为氧化剂的氧气。第三种由可再循环的水溶性钯-二胺络合物与作为氧化剂的空气在水性两相体系中结合组成。讨论了钌/克里思和钯催化氧化反应的机理，并将钌/TEMPO催化氧化反应的机理与铜/克里思催化氧化反应的机理进行了比较。
Three methods are described, in the context of the guiding principles of green chemistry, for the catalytic oxidation of alcohols. The first employs a recyclable oligomeric TEMPO catalyst (PIPO) and sodium hypochlorite as the oxidant in a bromide-free and chlorinated hydrocarbon solvent-free system. The second involves a ruthenium/TEMPO catalyst and oxygen as the oxidant. The third consists of a recyclable water-soluble palladium−diamine complex in conjunction with air as the oxidant in an aqueous biphasic system. The mechanisms of the ruthenium/TEMPO- and palladium-catalyzed oxidations are discussed, and the mechanism of the former is compared with that of the analogous copper/TEMPO catalyst.
