The nitration reaction of trichloroethene (1) to main products trichloronitroethene (TCNiE 2, up to 60.8 %, by GC), 1,1,2,2-tetrachloro-1-nitroethane (8, up to 25.1 %, by GC), and 1,2,2-trichloro-2-nitroethyl [chloro(nitro)methylene]azinate (9, up to 8.0 %, by GC) was comprehensively investigated and optimized. Different 1,1-diamino-2-chloro-2-nitroethenes, 2-nitroethoxyguanidines, and rare O-(1,2
三氯乙烯(1)硝化反应生成主要产物三氯硝基乙烯(TCNiE 2, 高达60.8 %, GC), 1,1,2,2-四氯-1-硝基乙烷(8, 高达25.1 %, GC),和 1,2,2-三氯-2-硝基乙基[氯(硝基)亚甲基] azinate(9,高达 8.0%,通过 GC)进行了综合研究和优化。不同的 1,1-二氨基-2-氯-2-硝基乙烯、2-硝基乙氧基胍和稀有的 O-(1,2,2-三氯-2-硝基乙基) 肟和碳酰亚胺酰卤,具有独特的分子式 R–O–N=C (NO2)NRR1 和 R–O–N=C(Hal)NRR1 分别以高达 91% 的产率从这些硝化产物中获得。(E)-morpholino(nitro)methanone O-(1,2,2-trichloro-2-nitroethyl)oxime (19) 的结构通过单晶 X 射线衍射分析得到证实。此外,还检测了合成化合物的抗微生物和抗真菌活性。值得注意的是,N-(1
