with a = 5.047 (18), b = 10.28 (4), c = 13.36 (5) Å, α = 107.59 (5)°, β = 93.55 (5)°, γ = 98.34 (5)°, and Z = 2. The unit cell of 6 has a monoclinic Pn symmetry with the cell parameters a = 9.581 (3), b = 12.217 (4), c = 11.072 (3) Å, β = 92.584 (4)°, and Z = 4. A series of 3,5-dichlorobenzamide compounds were synthesized from reactions of arylamine compounds with 3,5-dichlorobenzoyl chloride, which
3,5-二氯苯甲酰氯和芳胺化合物在 N,N'-二甲基甲酰胺溶液中在 60 °C 下反应,以良好的收率得到了一系列二氯苯甲酰胺衍生物 4-14。这些新化合物及其伴随的中间体通过核磁共振和红外光谱进行了表征和确认,其中化合物4和6的结构通过X射线晶体学确定。化合物4在三斜空间群Pī中结晶,a = 5.047 (18), b = 10.28 (4), c = 13.36 (5) Å, α = 107.59 (5)°, β = 93.55 (5)°, γ = 98.34 (5)°,Z = 2。6 的晶胞具有单斜 Pn 对称性,晶胞参数 a = 9.581 (3), b = 12.217 (4), c = 11.072 (3) Å, β = 92.584 (4)°,Z = 4。芳胺化合物与3,5-二氯苯甲酰氯反应合成了一系列3,5-二氯苯甲酰胺化合物,
