Aromatic and aliphatic sulfides are readily oxidized to sulfoxides or sulfones in high yield with 35% hydrogen peroxide in the presence of cyanuric chloride (CC) as an efficient activator. The oxidation of sulfides proceeds at room temperature and the corresponding sulfoxides or sulfones was selectively obtained by controlling the amounts of H2O2 and CC. Various sulfides possessing functional groups
在三聚氯氰 (CC) 作为有效活化剂的情况下,芳香族和脂肪族硫化物很容易以高产率被氧化成亚砜或砜,其中含有 35% 的过氧化氢。硫化物的氧化在室温下进行,通过控制 H2O2 和 CC 的量选择性地获得相应的亚砜或砜。具有羟基、甲氧基、腈、醛和烯烃双键等官能团的各种硫化物被成功地选择性氧化而不影响敏感的官能团。
Fe<sub>3</sub>O<sub>4</sub>/PEG-SO<sub>3</sub>H as a heterogeneous and magnetically-recyclable nanocatalyst for the oxidation of sulfides to sulfones or sulfoxides
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 / PEG-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 / PEG-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。
Sulfamic Acid–Catalyzed Oxidation of Sulfides to Sulfoxides and Sulfones Using H<sub>2</sub>O<sub>2</sub>: Green and Chemoselective Method
Abstract A mild, efficient, green, and selective oxidation method of sulfides to sulfoxides or sulfonesusing H2O2 in the presence of catalytic amounts of sulfamic acid has been developed. Various substituted sulfides having functional groups such as alcohol, ester, and aldehyde are successfully and selectively oxidized without affecting the sensitive functionalities in good to excellent yields at
