bluish-red colour develops immediately, but disappears within ca. 1 h. Comparison of the NMR. spectrum of this primaryproduct with model adducts of sulfiteions and di- and trinitrobenzene derivatives demonstrates that the primary addition of the nucleophile to 1-chloro-2, 4-dinitrobenzene does not take place at C (1), but at C(5). It is shown that the increments calculated for a C-SO group and for
