Room Temperature Ni(II) Catalyzed Hydrophosphination and Cyclotrimerization of Alkynes
Inorganics, 2018 The catalytic activity of nickel complexes in hydrophosphination involving secondary phosphines is not a commonly studied transformation. Beyond a small number of stand-out examples, many reports in the literature focus on the use of simple nickel salts.
