A comparison of two catalytic, metal-free iodoperfluoroalkylation protocols is presented.
Frustrated Lewis pairs [
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
of both reaction pathways are provided.
Key words
iodoperfluoroalkylation - frustrated Lewis pair - electron donor–acceptor complex
- halogenations - radicals
