The fluorination of 10-oxo-10H-5λ4,10λ4-thianthren-5-ylideneamine (2) with Selectfluor™ affords 5-fluoro-10-oxo-5,10-dihydro-5λ6,10λ4-thianthren-5-nitrile (4). The amination of 4 with morpholine gives 5-morpholino-10-oxo-5,10-dihydro-5λ6,10λ4-thianthren-5-nitrile (5). The stereochemical course of both reactions has been studied, while the configurations of their products, cis-isomer 4 and trans-5-morpholino-10-oxo-5
10-氧代- 10的氟化ħ -5λ 4,10λ 4 -thianthren -5-亚基胺(2)与的Selectfluor™得到5-氟-10-氧代-5,10-二氢5λ 6,10λ 4 -thianthren- 5-腈(4)。的胺化4与吗啉得到5-吗啉代-10-氧代-5,10-二氢5λ 6,10λ 4 -thianthren -5-腈(5)。两个反应的立体化学过程进行了研究,而他们的产品的配置中,顺式-异构体4和反式-5-吗啉代-10-氧代-5,10-二氢5λ 6,10λ 4X射线晶体学分析阐明了-thianthren-5-腈(trans - 5)。
