N-chlorosulfonylsulfamoyl chloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In the above embodiments, thionyl chloride (SOCl2), sulphamic acid (NH2—SO2OH) and chlorosulphonic acid (HSO3Cl) were mixed to allow the reaction to proceed in the first step. However, these reactants may be mixed stepwise. For example, sulphamic acid (NH2—SO2OH) is first mixed with thionyl chloride (SOCl2). After the sufficient reaction of the compounds is carried out, chlorosulphonic acid (HSO3Cl) is mixed thereto and subjected to heating. According to this procedure, the desired product of the first step, HN(SO2Cl)2 can also be obtained. the reaction However, these reactants may be mixed stepwise After the sufficient reaction of the compounds to heating

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The reaction of sulphamic acid with chlorosulphonic acid and thionyl chloride gives HN(SO2Cl)2. This reaction also provides by-products including sulphur dioxide, sulphuric acid and hydrochloric acid. Sulphur dioxide is generated from the reaction of thionyl chloride with sulphamic acid. Thus generation of sulphur dioxide indicates continuation of the reaction. Thus the heating is continued until generation of sulphur dioxide is ceased.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
