[36] cycloadduct 31 containing a CF3CCl2N= group. At 100 °C in solvent CH2Cl2, the isolated products were the isomers 9 (4%), 10 (4%) and 11 (5.5%), amide 14 (1%) and the reduced compounds 15 (6%) and 16 (19%) containing a CF3CH2N group. Reaction between hexafluoroacetoneazine (CF3)2C=NN=C(CF3)2 (5) and 7 at 70 °C was much cleaner and gave the bis[32] criss-cross cycloadduct 18 (15%), the bis-ene adduct
热反应的dichloroazine CF的(70℃)3的CCl = NN = CClCF 3,1,具有环庚三烯(7)得到的复杂混合物从其中主要产物分离,并确定为脱氯化氢重新排列[32] cycloadducts 9(28 %)和10(23%)含有CF 3 CHClN =基团,重排的1:1加合物(12或13)(4%)和酰胺14(18%)通过在硅胶上水解形成重排[36]含有CF 3 CCl 2 N =基团的环加合物31。在100°C的溶剂CH 2 Cl中如图2所示,分离出的产物为异构体9(4%),10(4%)和11(5.5%),酰胺14(1%)和含有CF的还原化合物15(6%)和16(19%)。3 CH 2 N组。六氟丙酮嗪(CF 3)2 C = NN = C(CF 3)2(5)与7在70°C之间的反应更清洁,得到bis [32]纵横交联的加合物18(15%),烯加合物20(17%)和偶氮化合
