The data described in the present article are in complete agreement with this proposition as they show that it was possible to trap these thiolactone sulfoxides by a series of nucleophiles such as amines , thiols , or cyclopentane - 1 , 3 - dione ( CPDH ) , an equivalent of dimedone that is used as a sulfenic acid trapping agent .
 Chemical: thiolactone sulfoxides; Chemical: amines; Chemical: thiols; Chemical: cyclopentane - 1 , 3 - dione; Chemical: CPDH; Chemical: dimedone; Chemical: sulfenic acid
