Bis(trifluoromethyl) disulfide (TFD) is a fluorinated organosulfur compound that was used as a fumigant.[1] It is also an intermediate in the synthesis of triflic acid. It is a volatile liquid that is extremely toxic by inhalation.
Synthesis[edit]
TFD can be produced by reaction of perchloromethyl mercaptan or thiophosgene with sodium fluoride.[2]
Toxicity[edit]
TFD is extremely toxic by inhalation. TFD is a powerful pulmonary agent that can cause severe pulmonary edema.[3] TFD is about half as toxic as perfluoroisobutene.[4]
