New ketosulfones have been prepared. Their chemical composition and structure were proved by analytical and spectral methods. The kinetics of 1,4-addition of arenesulfinic acids to 1,3-diphenyl-2-nitropropenone and 3-nitro-4-phenyl-3-butene-2-on were studied by LC. The overall reaction is second order, while it is first order regarding each reagent and substrate. On the basis of the experimental results
已经制备了新的酮砜。通过分析和光谱方法证明了它们的化学成分和结构。通过LC研究了芳烃亚磺酸1,4-加成到1,3-二苯基-2-硝基丙烯酮和3-硝基-4-苯基-3-丁烯-2-on的动力学。整个反应是二级反应,而对于每种试剂和底物来说都是一级反应。基于速率常数对温度的依赖性和取代基对速率的影响的实验结果,提出了亲核加成的可能机制。
