glycol-coated Fe3O4 nanocomposite (Fe3O4/PEG-SO3H) as a greatly effective and ecological nanocatalyst for the selective oxidation of sulfides to sulfoxides or sulfones with brilliant yields under solvent-free conditions by employing 30% hydrogen peroxide as the oxidant. A number of sulfides containing alcohol, ester, and aldehyde functional groups were fruitfully and selectively oxidized without altering the desired
我们在下面介绍一种磺化-聚
乙二醇涂层的Fe 3 O 4纳米复合材料(Fe 3 O 4 / P
EG-SO 3 H),它是一种非常有效的生态纳米催化剂,用于在溶剂中将
硫化物选择性氧化为亚砜或砜,并具有出色的收率。游离条件,采用30%的
过氧化氢作为氧化剂。在不改变所需特性的情况下,许多含有醇,酯和醛官能团的
硫化物被有效地和选择性地氧化。磁性纳米催化剂(Fe 3 O 4 / P
EG-SO 3H)可以通过使用外部磁性工具方便快捷地回收,并循环使用10多次以上,而不会显着降低其催化性能。
