Professor Rolf Huisgen Abstract A comparison of two catalytic, metal-free iodoperfluoroalkylation protocols is presented. FrustratedLewispairs [ t Bu3P/B(C6F5)3] or phosphines/phosphites under visible light irradiation efficiently mediate the functionalization of non-activated alkenes and alkynes. A comprehensive account of the corresponding substrate scopes as well as insights into the mechanistic details
纪念Rolf Huisgen教授 抽象 比较了两种催化的,无金属的碘代氟烷基化方案。沮丧的路易斯对[ t Bu 3 P / B(C 6 F 5)3 ]或膦/亚磷酸盐在可见光辐射下有效地介导了未活化的烯烃和炔烃的官能化。提供了对相应底物范围的全面介绍,以及对两种反应途径的机理细节的见解。

Catalytic amounts of zinc, as low as 10 mol %, in the presence of trifluoroacetic acid (TFA) initiate the radical addition of perfluoroalkyl iodides to terminal alkynes with high regio- and stereoselectivities. Palladium-mediated cross-coupling of these (E)-perfluoroalkyl vinyl iodides allows for a. facile synthesis of potentially useful fluoroorganic intermediates.
