Trichloromethanesulfenyl chloride → HCID 20356001, compound

Participants

Reaction Steps

To a solution of 38.2g (0.2 mole) 4-phenyl-1-methyl urazole in 200 ml water was added a solution of 8g (0.2 mole) sodium hydroxide in 20 ml water. A mixture of 37.2g (0.2 mole) trichloromethylsulfenyl chloride and 3g of an emulsifier solution (as in example 1) in 25 ml water was then added dropwise to the above basic solution while keeping the reaction mixture at 0° C. The reactants were mixed so that the reaction mixture was kept at a pH greater than 7. The precipitate that formed was filtered and the filter cake washed with water. After drying and recrystallizing from benzene-cyclohexane (1:1, by volume) there was obtained 65g (91%) 4-phenyl-1-methyl-2-(trichloromethylthio) urazole having a melting point of 154° C.
