(3-nitrophenyl)nitromethane (5), and (4-nitrophenyl)nitromethane (6) by the anions of substituted benzylmalononitrile (1-X-) in 90M Me 2 SO-10% water (v/v) at 20 o C is reported. Intrinsic rate constants and intrinsicbarriers of these reactions have been determined by extrapolation or interpolation of BrOnsted plots whose slopes (β) are all close to 0.5
9-氰基芴 (2)、1,3-茚二酮 (3)、4-硝基苯基-乙腈 (4)、(3-硝基苯基)硝基甲烷 (5) 和 (4-硝基苯基) 硝基甲烷可逆去质子化的动力学研究(6) 由取代的苄基丙二腈 (1-X-) 的阴离子在 90M Me 2 SO-10% 水 (v/v) 中在 20 o C 报告。这些反应的内在速率常数和内在势垒已通过斜率 (β) 均接近 0.5 的 BrOnsted 图的外推或内插确定
