(Chemical Equation Presented) A series of 1-acetyl(or phenyl)-3-aryl-5-(1- phenyl-3-methyl-5-aryloxyl-pyrazol)-4,5-dihydropyrazole derivatives have been efficiently synthesized under refluxing in glacial acetic acid with two kinds of hydrazines and five kinds of chalcones of 1-phenyl-methyl-5-phenoxyl-pyrazol-4- aldehyde. The structures were confirmed on the basis of 1H NMR, IR, MS and element analysis, and the crystal structure of the compound 4c was determined by single crystal X-ray diffraction. The compound 4c belongs to monoclinic system with space group P2(1)/n, a = 11.8779(3) nm, b = 12.0901(2) nm, c = 17.7004(4) nm, α = 90°, β = 100.05(10)°, γ = 90°, Formula weight: 549.46, Triclinic V =2502.89(9) nm3, D c =1.458 Mg/m3, Z = 4, F (000) = 1128.
