Synthesis and Crystal Structure of New Heterocyclic Compounds Containing 1,2,3-Triazole Moiety

Abstract  

A series of new heterocyclic compounds bearing 1,2,3-triazole moiety were synthesized using 4-acetyl-2-phenyl-1,2,3-triazole 1 as the starting material. The target compounds were prepared and the structures were characterized by IR, ¹H NMR, MS and elemental analysis. Meanwhile, the crystal structures of the synthesized compounds were also furthered confirmed by X-ray diffraction analysis. Compound 3b crystallized in the monoclinic P2(1)/c space group with unit cell parameters a = 10.6974(17) ?, b = 20.356(3) ?, c = 7.8049(12) ?, α = 90°, β = 102.840(3)°, γ = 90o, V = 1657.1(5) ?³, Z = 4, T = 293(2) K. Compound 7c crystallized in the Triclinic P-1 space group with unit cell parameters a = 7.364(2) ?, b = 7.366(2) ?, c = 26.089(8)?, α = 87.114(7)°, β = 87.040(7) (3)°, γ = 82.337(7)°, V = 1399.2(7) ?³, Z = 2, T = 293(2) K. Compound 10c crystallized in the Triclinic P-1 space group with unit cell parameters a = 9.8152(10) ?, b = 10.0806(13) ?, c = 11.1267(14) ?, α = 100.344(3)°, β = 111.975(3)°, γ = 107.852(3)°, V = 916.18(19) ?³, Z = 2, T = 293(2) K.
