本文测定了七个N-甲基-3-烷基-2-吡咯烷酮的~(13)C、~1H-NMR、IR和质谱,确定了各化合物的结构,并对谱线进行了归属。同时总结出烷基取代对吡咯烷酮的影响及吡咯烷酮对烷基化学位移的影响的~(13)C谱两组经验取代参数。
In this paper, ~ (13) C, ~ 1H-NMR, IR and mass spectra of seven N-methyl-3-alkyl-2-pyrrolidones were determined. The structures of the compounds were confirmed and the spectra were assigned. At the same time, two groups of empirical substitution parameters of ~ (13) C spectra of alkyl substituted on pyrrolidone and pyrrolidone on the chemical shift of alkylation were summarized.
