Abstract
The present invention relates to method for converting a sulfide of the following formula (I), such as yperite: R1—S—R2 (I) wherein R1 and R2, identical or different, are a (C1-C3)alkyl, (C2-C3)alkenyl, aryl, aryl-(C1-C3)alkyl, or aryl-(C2-C3)alkenyl group, said group being optionally substituted by one or several groups selected from a halogen atom, OR3, and NR4R5, and R3, R4, and R5 are, independently of one another, H or a (C1-C3)alkyl; into a sulfoxide of the following formula (II): R1—SO—R2 (II) wherein R1 and R2, are as defined above, wherein said method comprises oxidizing the sulfide of formula (I) in the presence of a catalyst. under an atmosphere comprising dioxygen, and under white or blue light irradiation, wherein the catalyst has the following formula (I): wherein Ar1, Ar2, Ar3, and Ar4 are, independently of one another, an aryl group optionally substituted by one or several groups selected from halogen, a (C1-C3)alkyl, OR6, and NR7R8, and R6, R7, and R8 are, independently of one another, H or a (C1-C3)alkyl. The present invention relates also to an air-filtering device comprising a catalyst of formula (I).
