The CsF-assisted reactions of syn and anti-NCCFNF with Cl2 and Br2 and the uncatalyzed addition of ClF are described. Chlorine reacts only with the imine function, whereas Br2 reacts with both carbon-nitrogen multiple bonds. The more reactive syn isomer is isomerized to the anti- isomer under the reaction conditions. Six new compounds are reported and their structures assigned by 19F NMR and infrared
描述了顺式和反式-NCCF = NF与Cl 2和Br 2的CsF辅助反应以及ClF的未催化添加。氯仅与亚胺官能团反应,而Br 2与两个碳-氮多键反应。在反应条件下,反应性更高的顺式异构体被异构化成反异构体。报告了六个新化合物,并通过19 F NMR和红外光谱对它们的结构进行了分配:Cl 2 NCF 2 CF 2 NClF I,NCCF 2 NClF II,NCCF 2NFBr III,SYN - BrNCFCFNF IV,顺-Br-NCFCF 2 NBRF V,和顺式-BrNCFCF 2 NCLF VI。
