The reaction of the oxadiazapentane (CF3)2NON(CF3)2 (1) with the alkenes CH2=CHX (X=Br, Cl, Ph, CN), CH2=CX2 (X=Cl, F), CHCl=CCl2 and CF2=CCl2 at c. 20 °C gives in each case a single 1:1 adduct formed via initial (CF3)2N· radical attack. With the alkene CH2=CHF, bidirectional radical attack occurs to afford the 1:1 adducts (CF3)2NCH2CHFON(CF3)2 and (CF3)2NCHFCH2ON(CF3)2 in the ratio 94:6, while with
恶二氮杂戊烷(CF 3)2 NON(CF 3)2(1)与烯烃CH 2 = CHX(X = Br,Cl,Ph,CN),CH 2 = CX 2(X = Cl,F)的反应,CHCl = CCl 2,CF 2= CCl 2在c。在每种情况下20°C都会通过初始(CF 3)2 N·自由基攻击形成单个1:1加合物。在烯烃CH 2 = CHF的情况下,发生双向自由基攻击,得到1:1的加合物(CF 3)2 NCH 2 CHFON(CF 3)2和(CF 3)2 NCHFCH 2 ON(CF 3)2的比例为94:6,而在(E)-CHCl = CHCl的情况下,会形成赤型和苏型1:1加合物的混合物(比例为70:30) 。的反应1与烯烃的CCl 2 =的CCl 2在50℃下使肼(CF 3)2 NN(CF 3)2(39%),1:1加合物(CF 3)2 NCCL 2的CCl 2 ON( CF 3)2(21%)和羟基(CF
