Telomerisation reactions have been investigated for the alkenes 1,1-difluoroethene (5) and hexafluoropropene (3) with the telogens CF2Br2 (1), CF3CFBr2 (8) and CF3CBr3 (9), as a means of preparing telomers and co-telomers. The efficiency of chain transfer increases as 1⩽8<9. Surprisingly, co-telomerisations of 5 with 3 occurred more efficiently than the corresponding telomerisations with 5 alone. The
研究了端链反应剂CF 2 Br 2(1),CF 3 CFBr 2(8)和CF 3 CBr 3(9)与烯烃1,1-二氟乙烯(5)和六氟丙烯(3)的端粒化反应。制备端粒和共端粒的方法。链转移的效率随着1⩽8<9的增加而增加。令人惊讶的是,5和3的共端粒化比单独5的相应端粒化更有效。描述了溶剂的作用。
