Peroxide in, phenol out: The catalyst γ-PW(10)O(38)V(2)(μ-OH)(2) showed high activity in the hydroxylation of various aromatic compounds with aqueous H(2)O(2). The system was regioselective, producing para-phenols from monosubstituted benzene derivatives. Furthermore, alkylarenes with reactive side-chain C sp 3-H bonds could be chemoselectively hydroxylated without significant formation of side-chain oxygenated products.
过氧化物进,酚类出:催化剂γ-PW(10)O(38)V(2)(μ-OH)(2)在以水合 H(2)O(2)对各种芳香族化合物进行羟基化反应时表现出很高的活性。该体系具有区域选择性,能从单取代苯衍生物中生成对苯二酚。此外,具有反应性侧链 C sp 3-H 键的芳基烷基可以被化学选择性地羟化,而不会显著生成侧链氧化产物。
