摘要
The title compound（S）-N-（2-oxoazepan-3-yl）biphenyl-4-carboxamide（C19H20N2O2, Mr = 308.37） was synthesized by the reaction of（S）-α-amino-∑-caprolactam with 4-phenyl-benzoyl chloride. Its chemical structure was determined by 1H NMR, 13 C NMR, H RMS and X-ray single-crystal diffraction. The crystal belongs to the triclinic system, space group P1 with a = 8.2650（17）, b = 13.774（3）, c = 15.109（3） A, β = 90.20（3）o, V = 1645.6（6） A3, Z = 4, Dc = 1.245 g/cm3, μ = 0.081 mm-1, F（000） = 656, R = 0.0756 and w R = 0.1491 for 5964 observed reflections with I 〉 2σ（I）. The title compound was also used to prepare polyamide.
