在羰基-三(三苯基膦)氢化铱(Ⅰ)催化下,氟烷基碘1与烯烃2加成得到高产率的加成产物,反应条件温和,有良好的选择性.氟烷基碘1也可与炔烃4反应,生成以 E 式异构体占优势的氟烷基化烯烃.反应体系中加入自由基抑制剂或单电子转移阻止剂则大大减慢反应;二烯丙基醚可以捕获自由基生成四氢呋喃衍生物;光电子能谱表明部分一价铱在反应后价态升高,这些事实表明反应为单电子转移引发下的自由基链式机理. Under the catalysis of carbonyl-tris (triphenylphosphine) iridium (I), the addition of fluoroalkyl iodide 1 to alkene 2 gives a high yield of adduct with mild selectivity and good selectivity. 1 can also react with alkyne 4 to form fluoroalkylated olefins which predominate with the E-type isomer.The addition of a radical inhibitor or a mono-electron transfer blocker to the reaction system greatly slows the reaction; diallyl ether Can capture free radical generated tetrahydrofuran derivatives; photoelectron spectroscopy shows that part of the monovalent iridium in the reaction valence increased, these facts show that the reaction is a single electron transfer induced by the free radical chain mechanism.
