1-酰基-5-芳基双缩脲类化合物的质谱研究

Mass spectra of 1-Acyl-5-Aryl-Biurets

本文报道了14个新的1-酰基-5-芳基双缩脲类化合物的电子轰击质谱。根据高分辨质谱及联动扫描质谱揭示了该类化合物的质谱裂解途径,结果表明该类化合物出现较强的分子离子峰及特征的基峰[ArNCO]^+。

The EI mass spectra of the new 14 1-acyl-5-aryl-biurets were reported. Their mass spectral fragmentations were proposed on the basis of high resolution mass spectrometry and B/E linked scan spectra. The results show that the molecular ion is relatively strong, and the characteristic peak [ArNCO]^+ is a base peak.
