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