Here, we report an intermolecular carboacylation of terminal alkynes with tertiary and secondary alkyltrifluoroborates as well as acyl chlorides via photoredox/nickel dual catalysis, affording a varity of stereodefined trisubstituted enones in good to excellent yields and stereoselectivity, through a radical relay process. This redox-neutral protocol exhibits excellent functional group tolerance, exclusive regio- and stereoselectivity, and broad compatibility with various acyl chlorides and alkyltrifluoroborates.

A novel photoredox/nickel dual catalytic intermolecular alkylarylation of vinylarenes with tertiary and secondary alkyltrifluoroborates and aryl bromides is described, which affords 1,1-diarylalkane frameworks that are found in various natural products as well as functionalized molecules in good to excellent yield and regioselectivity through a radical relay process. Notably, this redox-neutral reaction could proceed efficiently with good tolerance of various substrates, including a great diversity of commercially available (hetero)aryl bromides, alkyltrifluoroborates, and vinylarenes.
