We prepared magnetically recoverable osmium catalysts by use of magnetite, quaternary ammonium salts, and potassium osmate(VI), and applied them to the dihydroxylation of olefins. By employing 2 mol% of the magnetic osmium catalyst, the dihydroxylation reaction proceeded smoothly to provide the corresponding vicinal diol in a good chemical yield. The osmium catalyst was readily recovered by use of
我们利用磁铁矿,季铵盐和osmate钾(VI)制备了可磁回收的m催化剂,并将其应用于烯烃的二羟基化反应。通过使用2mol%的磁性催化剂,二羟基化反应顺利进行,以良好的化学产率提供相应的邻位二醇。an催化剂可通过使用外部磁体容易地回收,并重复使用。
