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。

The remarkably stable crystalline perhydrate 1 derived from α-bromocyclohexanone has been characterised by X-ray crystallography providing the first example of a perhydrate crystalstructure. Perhydrate 1 exists in alternative chair conformations in chloroform and tetrahydrofuran with the bromine substituent occupying equatorial and axial positions, respectively. The perhydrate 1 can oxidise sulfides

catalyst [MoO3(2,2′–bipy)]n has been employed in the oxidation of secondary amines to nitrones, and sulfides to sulfoxides or sulfones, using tert–butylhydroperoxide (TBHP) as the stoichiometric oxidant. Whereas the oxidation of amines occurs with less proficiency with respect to other previously studied polymeric Mo catalysts, the oxidation of sulfides occurs in high yield and selectivity. The catalyst
