N,N’-Di(p-toluenesulfonyl)-1,8-diaza[8.1]paracyclophane-15-sulfone (C), N,N’-di(p-toluenesul- fonyl)-1,10-diaza[10.1]paracyclophane-17-sulfone (D) and N,N’-di(p-toluenesulfonyl)-1,12-diaza[12.1]- paracyclophane-19-sulfone (E) were synthesized under a high dilution condition by the cyclization between dibromide and N,N’-di(p-tosylamino)diphenylsulfone (B), which was prepared using 4,4’-diamino diphenyl sulfone and p-toluenesulfonyl chloride as raw materials. The structures were confirmed by IR, 1H NMR and elemental analysis. The crystal structure of compound D was determind, which can provide the basis for study of structures of cyclophane compounds.

Key words: azaparacyclophane, synthesis, characterization, crystal structure
