摘要
合成了异丙基糠硫基吡嗪(Ⅰ)、异丁基糠硫基吡嗪(Ⅱ)、异丙基甲硫基吡嗪(Ⅲ)和异丁基甲硫基吡嗪(Ⅳ)。其中Ⅰ和Ⅱ为新化合物。经红外光谱、核磁共振谱、质谱和C、H、N元素分析及对其质谱断裂规律作了研究,证明其结构与预期的一致。
In this paper, isopropyl furfuryl thio-pyrazin (Ⅰ), isobutyl furfuryl thio-pyrazine (Ⅱ), isopropyl methyl thiopyrazine (Ⅲ), isobutyl methyl thiopyrazine (Ⅳ) were synthesized. (Ⅰ) and (Ⅱ) are new compounds. Their structures were identified by IR, NMR and C.H.N analyser. The mass spectra of these compounds were studied.
