To our delight, the protocol could also be extended to radical group transfer of alkynes (Scheme 3). Analogous alkynyl silane substrates 7f, 7k and 7s were prepared from iodohydrins 3 by treatment with an alkynyl aminosilane (see the Supplementary Information). After undergoing radical group transfer and desilylation, we obtained products alkynylated at secondary (8f), primary (8k) and benzylic (8s) positions. Under the acidic desilylation conditions, the trimethylsilyl substituent on the alkyne remains intact.
