Kinetic pressure and solvent effects were studied for geometrical isomerization about carbon-nitrogen double bond in N,N-dimethyl-N′-[(4-nitrophenyl)methylene]-1,4-benzenediamine and 4-[[4-(dimethylamino)phenyl]imino]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-one. In both of the compounds, the effects clearly demonstrate that the polarity of the reactant decreases slightly during activation, and the
研究了N,N-二甲基-N'-[(4-硝基苯基)亚甲基]-1,4-苯二胺和4-[[4-(二甲氨基)苯基]亚氨基]-2,4-二氢-5-甲基-2-苯基-3H-吡唑-3-one。在这两种化合物中,效果清楚地表明,在活化过程中反应物的极性略有下降,结果很难与先前提出的旋转机制相一致。
