Novel N,N'-bis(trifluoromethylsulfonyl)oxamides of the formula (I)
wherein R and R' have the meaning given in the description (preferably chlorinated phenyl or pyridyl, nitrophenyl or methoxyethyl), when used in compositions comprising
also an organic fluorescer such as 1-chloro-9,10-bis(phe- nylethynyl)-anthracene and a diluent such as dibutyl phthalate, will furnish chemiluminescent light with good light intensity and quantum efficiency upon reaction with a peroxide component such as hydrogen peroxide. The preparation of the compounds of the formula (I) is described; e.g. the particulary preferred compound N,N'-bis(2,4,5-trichlorophenyl)-N,N'-bis-trifluoromethylsulfonyl)-oxamide is prepared on the following way:
新颖的 N,N'-双(三氟甲基磺酰基)草酰胺,其式为(I)
其中 R 和 R'具有说明中给出的含义(最好是氯化苯基或吡啶基、硝基苯基或甲氧基乙基),当用于包含以下成分的组合物中时
当与过氧化物成分(如过氧化氢)反应时,将产生光强度和量子效率良好的化学发光。例如,N,N'-双(2,4,5-三氯苯基)-N,N'-双三氟甲基磺酰基)-氧酰胺的制备方法如下:

The sulfonamides CF3SO2N(CH3)Na and CF3SO2N(H)Na have been reacted with polyfluoro cyclic, acyclic and inorganic chlorine and bromine-containing species. Nucleophilic displacement of chlorine or bromine in 1,2-dichloroperfluorocyclobutene, 1,2-dichloroperfluorocyclopentene, benzyl bromide, cyanuric chloride and oxalylchloride has been found to occur under mild conditions to give good yields of N-substituted
