Abstract: Abstract Reaction of N,N'-diphenyl-1,3-benzene-bis-carbohydrazonoyl bromide 3 with potassium thiocyanate, potassium selenocyanate, active methylene compounds and dipolarophilic alkenes were studied. Structures of the products were established on analytical and spectral data as well as chemical transformations.… read more here.
