Trichloromethanesulfenyl chloride → HCID 20355997, compound

Participants

Reaction Steps

To a solution of 24.6g (0.1 mole) 4-(3,4-dichlorophenyl)urazole in 100 ml water was added a solution of 8g (0.2 mole) sodium hydroxide in 10 ml water. A mixture of 37.2g (0.2 mole) trichloromethylsulfenyl chloride and 1.5g of an emulsifier solution (as in example 1) in 25 ml water was added dropwise to the above basic solution while keeping the reaction mixture at 0° C. The precipitate that formed was filtered and the filter cake was washed with water. After drying and recrystallizing from benzene there was obtained 48g (87%) of 4-(3,4-dichlorophenyl)-1,2-bis(trichloromethylthio)urazole having a melting point of 167° C.
