Complexation versus thiadiazole formation for reactions of thiosemicarbazides with copper(II).
The reactions of N,N-substituted thiosemicarbazides with copper salts have been investigated and either copper(II) thiosemicarbazide complexes, 1,3,4-thiadiazolium salts or 1,3,5-thiadiazoles are obtained depending on the Cu(II) salt and solvent used.
