以1-苯基-3-甲基-吡唑啉酮-5 (PMP)和1,3-二苯基-吡唑啉酮-5 (DPP)为原料合成了六种4-酰基吡唑啉酮,并分别与氨基脲缩合,得到六个新的含吡唑啉酮环的缩氨基脲类化合物.用IR, 1H NMR和13C NMR对各化合物进行了表征及结构确证,并用X射线单晶衍射法测定了化合物1c [1-苯基-3-甲基-4-丙酰基-吡唑啉酮-5缩氨基脲(PMPP-SC)]的晶体结构.

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.

Key words: 4-acylpyrazolone, semicarbazide, crystal structure
