Abstract
| - The mixed reagent SnC(SiMe3)2CH2CH2C(SiMe3)2]/ArI reacts with alkynes to give primary and secondary propargylic C−H activation. Alkynes tested include 1-phenylpropyne, 1-phenylbutyne, 1-trimethylsily1hexyne, and 2-hexyne. Aryl halides tested include iodobenzene and 2,4,6-triisopropyliodobenzene. An X-ray crystal structure is reported for the product of the secondary propargylic activation of 2-hexyne.
