The passage of dry gaseous hydrogen chloride through chloroform solutions or acetone suspensions of S-substituted N/sup 1/,N/sup 4/-di(salicylidene)isothiosemicarbazidates of nickel (Ni(LRR')) has led to a demetallization reaction with the liberation in the free state of S-substituted N/sup 1/,N/sup 4/-di(salicylidene)isothiosemicarbazides with the general formula N/sub 2/LRR' (where R is H and R' is CH/sub 3/ (I); R is H and R' is C/sub 2/H/sub 5/ (II); R is H and R' is C/sub 3/H/sub 7/ (III); R is H and R' is C/sub 7/H/sub 7/ (IV); and R is CH/sub 3/ and R' is CH/sub 3/ (V)). The IR spectra of (I-IV) each showed bands characteristic for an aromatic ring in the 1600-1500 cm/sup -1/ region, with a band of the deformation vibrations of an OH group at 1300 cm/sup -1/. The PMR spectra in CDCl/sub 3/ each had two singlets at 12.15-11.25 and 9.00-8.36 ppm which were assigned, respectively, to the protons of an OH group and those of a =CH group. A multiplet in the 7.70-6.83 ppm region belonged to the protons of benzene rings. In the region of lower fields there were the signals of the substituents R and R'. In the mass spectra of (I-V), the peaks of the molecular ions, and also the characteristic fragments OH, R', SR', and HSR' have been detected.
