Six kinds of 4-acylpyrazolone were synthesized from 1-phenyl-3-methyl-5-pyrazolone (PMP) and 1,3-diphenyl-5-pyrazolone (PPP), and then six new compounds of semicarbazone containing pyrazolone: 1-phenyl-3-methyl-4-acetyl-5-pyrazolone semicarbazone (PMAP-SC) (1a), 1-phenyl-3-methyl-4-chloracetyl-5-pyrazolone semicarbazone (PMCP-SC) (1b), 1-phenyl-3-methyl-4-propionyl-5-pyrazolone semicarbazone (PMPP-SC) (1c), 1,3-diphenyl-4-acetyl-5-pyrazolone semicarbazone (DPAP-SC) (2a), 1,3-diphenyl-4-chloracetyl-5-pyrazolone semicarbazone (DPCP-SC) (2b), and 1,3-diphenyl-4-propionyl-5-pyrazolone semicarbazone (DPPP-SC) (2c), were synthesized by direct condensation of the pyrazolone with semicarbazide (SC). The products were characterized by elemental analysis, IR, 1H NMR and 13C NMR spectra. The crystal structure of compound 1c was determined by X-ray diffraction analysis. 1c belongs to the monoclinic system with space group C2/c and cell dimensions: a=2.3590 nm, b=0.9456 nm, c=1.3319 nm, β=101.65(2)°, V=2.9098(8) nm3, Z=8, Dc=1.312 g/cm3, F(000)=1216, R1=0.0348, wR2=0.0913.
