四(五氟苯基)卟啉铁在EtOH中催化的H 2 O 2氧化硫化物是一种有效的化学选择过程。在催化剂浓度为底物浓度的0.03-0.09%的情况下,获得的亚砜的收率通常约为分离产物的90-95%。对于乙烯基和烯丙基硫化物,未观察到环氧化。催化剂浓度为底物浓度的0.09%至0.25%,可以以几乎定量的产率获得砜,并且在亚砜的合成中观察到相同的高化学选择性。

Synthesis of Sulfoxides by the Hydrogen Peroxide Induced Oxidation of Sulfides Catalyzed by Iron Tetrakis(pentafluorophenyl)porphyrin: Scope and Chemoselectivity
The oxidation of sulfides with H2O2 catalyzed by iron tetrakis(pentafluorophenyl)porphyrin in EtOH is an efficient and chemoselective process. With a catalyst concentration 0.03−0.09% of that of the substrate, sulfoxides are obtained with yields generally around 90−95% of isolated product. With vinyl and allyl sulfides, no epoxidation is observed. With a catalyst concentration between 0.09% and 0.25%
