Reactions of 1,2-diphenyl-4benzylidine-3,5-dichloro-pyrazolium perchlotrate with some amines

ABSTRACT

The chemistry of 3,5 pyrazolidinediones and 3-[substituted] -l,2-diphenyl-3-pyrazolin-5-ones has received much importance since the discovery of the remarkable anti-inflammatory property exhibited by many members of these classes. This investigation describes the preparation of l,2-diphenyl-4-benzylidine-3,5-bis [dialkyl or heterocyclic - amino] pyrazolium perchlorate, using l,2-diphenyl-3,5-pyrazolidinedione as a starting material. Action of alcoholic NaOH on the perchlorate salts, IR and NMR spectra of the new products are also investigated
