我们曾报道了α-噻吩甲酰基次甲基三苯肺、Ⅰ)的合成及其质谱裂解的主要特征碎片峰。本文报道(Ⅰ)裂解途径及其反应产物的质谱。其质谱测试条件:质谱仪为 VG-ZAB-HF-3F 型。电子撞击电离电压70eV,离子源温度为200℃,直接进样杆的探头温度不加热。视样品的不同分辩本领在1800～5000范围。它的质谱除了分子离子峰(M_(·~+)m/e 430以外,还有 m/e 347(M-83)~+,m/e 306(M-124)~+,m/e 229(M-124-77)~+,m/e 227(M-124-77-2)~+,m/e 152(M-124-77-2-75)等特征峰,其结构式和裂解途径见图1.
We have reported the synthesis of α-thenoylmethine tribenzyl lung, Ⅰ) and the main characteristic fragment peaks of its mass spectrometry. This paper reports (I) the cleavage pathway and the mass spectrum of its reaction product. The mass spectrometry test conditions: mass spectrometer VG-ZAB-HF-3F type. Electron impact ionization voltage 70eV, the ion source temperature is 200 ℃, the temperature of the probe directly probe is not heated. Depending on the sample different skills in the 1800 to 5000 range. In addition to the molecular ion peak (M_ (~ +) m / e 430, m / e 347 (M-83) ~ +, m / e 306 (M-124) ~ +, m / e 229 (M-124-77) ~ +, m / e 227 (M-124-77-2) ~ +, m / e 152 (M-124-77-2-75). The structural and cleavage pathway see picture 1.
