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。
By means of the temperature-changing experiment and the DPFGSE NOE experiment, two new 5 (3-chlorophenyl) 2 furfural N 4 methylphenoxyacetylhydrazone and 5 (3 chlorophenyl) 2 furancarbaldehyde N 4 nitrophenoxyacetylhydrazone were determined. The spatial configuration of the compounds in dimethylsulfoxide at 25 ℃ and the total chemical shifts of these two new compounds at 25 ℃ and 90 ℃.
