C15H15NOS, Mr = 257.35, monoclinic, P2(1), a = 7.710 (2), b = 5.903 (5), c = 14.700 (3) A, beta = 91.48 (2) degrees, V = 668.8 (6) A3, Z = 2, Dx = 1.278 g cm-3, lambda(Mo K alpha) = 0.71069 A, mu = 2.18 cm-1, F(000) = 272, T = 296 K, R = 0.043, 944 unique observed reflections. This is the first structure determination of an N-alkylidenesulfinamide. The C = N bond is distorted and lengthened presumably because of the steric interaction and electron-withdrawing effect of the sulfinyl group. The nonplanar conformation is also a result of repulsive steric interaction. The configuration at C = N is trans. The title compound was obtained from the displacement reaction of (-)-1-methyl (S)-p-toluenesulfinate with methyllithium.
C15H15NOS，Mr = 257.35，单斜晶系，P2(1)，a = 7.710 (2)，b = 5.903 (5)，c = 14.700 (3) Å，β = 91.48 (2)°，V = 668.8 (6) ų，Z = 2，Dx = 1.278 g cm⁻³，λ(Mo Kα) = 0.71069 Å，μ = 2.18 cm⁻¹，F(000) = 272，T = 296 K，R = 0.043，944个独立观测反射。这是首次对N - 亚烷基磺酰胺进行结构测定。C = N键发生扭曲并变长，可能是由于亚磺酰基的空间相互作用和吸电子效应。非平面构象也是空间排斥相互作用的结果。C = N处的构型为反式。标题化合物由(-)-1 - 甲基(S)-对甲苯亚磺酸盐与甲基锂的取代反应制得。
