Description
  • The reaction between 5-nitro-2,1-benzisothiazole-3-diazonium species and N-substituted anilines produces the 1(5-nitro-2,1-benzisothiazol-3-yl)-3,3-disubstituted triazenes 1. These triazenes are highly stable, and even in strongly acidic medium (0,5 mol.L-1 H2SO4) they are only slowly decomposed back to the diazonium ion and substituted anilinium ion (for the N-ethyl derivative in 0,5 mol.L-1 H2SO4 at 25 degreesC, t(1/2) approximate to 7 h). A series of six triazenes were characterised by their H-1 and C-13 NMR spectra and mass soectra. Two of the triazenes were also identified by X-ray crystallography.
