Synthesis

Trichloronitrosomethane can be produced with following methods:^[1][2]

• Oxidation of trichloromethylsulfinic acid with nitric acid.
• Reaction of sodium trichloromethylsulfinate with sodium nitrite and sodium nitrate or potassium nitrate in sulfuric acid.
• Pyrolysis of trichloroacethydroxamic acid.

Chemistry

Trichloronitrosomethane is an unstable substance. It slowly decomposes into nitrosyl chloride, nitrogen oxides, and chloropicrin over time.^[1]

Trichloronitrosomethane can be reduced to phosgene oxime by hydrogen sulfide.^[1]
