本文采用酰氯路线由甲基丙烯酰氯同苯胺、对甲苯胺、邻甲苯胺、对溴苯胺、对硝基苯胺、邻硝基苯胺、α-萘胺等反应制得了一系列N-芳基取代甲基丙烯酰胺(N-ArMA)。给出了这些新单体的~1H-NMR谱图.研究了这些单体中苯环上不同取代基及同一取代基在不同取代位置上对质子的化学位移的影响.研究结果表明,不同的取代基由于不同的电子效应使苯环上质子峰发生位移,按向低场位移顺序是:-NO_2>-Br>-H>-CH_3同样的取代基在邻位取代使苯环质子移向低场更显著。化学位移的实测值与经验公式计算值比较一致。
In this paper, a series of N-aryl-substituted methylene-N-substituted a Basic acrylamide (N-ArMA). The ~ 1H-NMR spectra of these new monomers are given. The effects of different substituents on the benzene rings and the same substituents on the chemical shifts of the protons at different substitution positions are studied. The results show that different Substituents shift the proton peak on the benzene ring due to different electronic effects. The order of the shift to the lower field is: -NO 2> -Br> -H> -CH 3 The same substituents are substituted in the ortho position to move the benzene ring protons to low Field more significant. The measured value of chemical shift is in good agreement with the empirical formula.
