Abstract
AbstractThe catalytic system based on Fe(OTf)2 (2.5 mol%) and DABCO (1 mol%) selectively promotes the dehydrogenative borylation of both aromatic and aliphatic terminal alkynes to afford alkynylboronate derivatives in the presence of 1 equiv. of pinacolborane at 100 °C in toluene. This methodology is applicable to a variety of terminal alkynes (16 examples, yield: 62–93%).magnified image
