The reaction of aromatic aldehydes with thiosemicarbazide gives arylidene hydrazinecarbothioamide, whose
reaction with phenacyl bromide, yielded (arylidenehydrazonyl)-4-phenylthiazole. The structures of 3 and 7 were fully
characterized by using 1H-NMR and mass spectroscopic techniques. The spectral analysis agreed with the assigned structures.
The assigned structures were further supported by single-crystal X-ray diffraction studies and summarized as follows:
(3) Triclinic, P-1, a=7.6319(4) Å, b= 8.7099(4) Å, c=10.7145(5) Å, α= 77.7400 (10)°, β= 74.0160 (10)°, and
γ= 72.8270 (10)°, V= 647.47(5) Å3, and Z = 2; (7) Orthorhombic, Pna21, a = 9.3760(13), b = 14.029(2), c = 23.591(3)Å,
α=90, β= 90, and γ= 90o, V = 3103.0(7)Å3, and Z = 4.
芳香醛与氨基硫脲反应生成亚苯基酰肼硫酰胺,其与苯乙酰溴反应生成(亚苯基酰肼基)-4-苯基噻唑。通过1H-NMR和质谱技术全面表征了3和7的结构。光谱分析与所指派的结构一致。所指派的结构进一步得到了单晶X射线衍射研究的支持,总结如下:3为三斜晶系,P-1空间群,a=7.6319(4) Å,b=8.7099(4) Å,c=10.7145(5) Å,α=77.7400(10)°,β=74.0160(10)°,γ=72.8270(10)°,V=647.47(5) ų,Z=2;7为正交晶系,Pna21空间群,a=9.3760(13) Å,b=14.029(2) Å,c=23.591(3) Å,α=90°,β=90°,γ=90°,V=3103.0(7) ų,Z=4。
