twisted vs. the aromatic ring, there is no conjugation between the nitro and nitramino groups across the ring. The nitramino group is an electron withdrawing substituent due to the inductive effect. The number and positions of the Ar-nitro groups have no influence on the N-nitro group. Its migration ability cannot be explained in terms of the interaction between the migration origin and the ring substituents
摘要 采用光谱和电光方法制备并研究了N-甲基-N-苯基硝胺的10种单、二和三硝基衍生物。其中三个,即。N-(2, 5-dinitrophenyl)-N-methylnitramine (monoclinic, P21/c, a=8.248(2), b=11.655(2), c=10.404(2) A, β=102.57(2)°) , N-(2,3-二硝基苯基)-N-甲基硝胺 (单斜, P21/c, a=9.224(2), b=7.222(2), c=15.458(4) A, β=101.08(2)° )) 和 N-(3,5-二硝基苯基)-N-甲基硝胺 (单斜, P21/n, a=9.814(2), b=12.000(2), c=8.865(2) A, β=114.94(2) )°) 通过 X 射线衍射法进行检测。硝基氨基几乎是平面的,具有短的 N(7)-N(8) 键和强烈缺电子的 N(8)
