摘要:

利用变温实验和DPFGSE-NOE实验,确定了5-(3-氯苯基)-2-呋喃甲醛-N-4-甲基苯氧乙酰腙和5-(3-氯苯基)-2-呋喃甲醛-N-4-硝基苯氧乙酰腙两个新化合物25 ℃时在二甲基亚砜中的空间构型,并对这两个新化合物在25 ℃和90 ℃时的质子的化学位移进行了全归属。

Abstract:

The stereochemical structures of two new compounds, 5-(3-chlorophenyl)-2-furfur-aldehyde-N-4-methylphenyloxyacetylhydrazone and 5-(3-chlorophenyl)-2-furfuraldehyde-N-4-nitrophenyloxyacetylhydrazone, were determined by DPFGSE-NOE experiments performed in DMSO-d6 at 25 ℃ and variable-temperature 1H NMR. The 1H chemical shifts of the compounds were completely assigned at 25 ℃ and 90 ℃.

Key words: 1H NMR, variable-temperature, DPFGSE-NOE, assignments, 5-(3-chlorophenyl)-2-furfuraldehyde-N-aryloxyacetylhydrazones
