A new, polymer-bound reagent system for the efficient oxidation of primary alcohols to aldehydes and secondary alcohols to ketones in the presence of a catalytic amount of 2,2,6, 6-tetramethyl-1-piperidinyloxyl (TEMPO) is described. In most cases, workup of this heavy metal-free oxidation is achieved by simple filtration followed by removal of the solvent. In selected examples this reagent was compared
描述了一种新的,与聚合物结合的试剂系统,用于在催化量的2,2,6,6-四甲基-1-哌啶基氧基(TEMPO)存在下将伯醇有效氧化为醛,将仲醇有效氧化为酮。在大多数情况下,这种无重金属氧化的后处理是通过简单的过滤然后除去溶剂来实现的。在选定的示例中,将该试剂与已知的聚合物结合的高锰酸盐和铬(VI)试剂进行了比较。
