Benchtop nickel-catalyzed reductive coupling of aldehydes with alkynes and ynamides.

We demonstrate the potential of Ni(COD)(DQ), a bench-stable Ni 0 complex, as a catalyst for the reductive coupling of aldehydes with alkynes and ynamides, providing silylated allyl alcohols with excellent yields and regioselectivities. Mass spectrometric identification of the intermediates and DFT studies supported the proposed mechanism.
