2016/7/21
Following Nara in Japan in 2012, Paris is honored to host the joint conference 13th International Conference on Radiation Shielding (ICRS-13) & 19th Topical Meeting of the Radiation Protection & Shi...
摘要 用典型自由基引发(hv,Cu,S2O4^2^-,ABN,DBP等),可以使2-卤四氟碘乙烷(1)(XCF2CF2I,X=Cl,I)产生四氟乙烯.从而证实了2-卤四氟乙基自由基在温和实验条件下能够发生β-断裂.1与亲核试剂(如PPh3,F^-,Cl^-,Br^-,CH3O^-,PhS^-等)作用结果,同样能得到四氟乙烯.这是符合离子型亲卤反应机理的.由此可见,1具有参与自由基机理和亲卤机理反应...
