Abstract Treatment of dialkylamidosulphonyl chlorides or bromides with trimethylamine affords stable crystalline 1∶ 1 addition compounds of the general formula [R 2 NSO 2 N (CH 3) 3]+ X−(cf. Table 1). Evidence for this formulation is obtained from IR spectra. A striking difference between these compounds and the parent sulphonyl halides is the enhanced reactivity of the halogen groups. The thermal degradation and the reactions of the ...
