    Lewis Base Adducts of Phosphine-Stabilized Pb(II) Cations: Synthesis and Catalytic Hydroamination of Alkynes
    (2022) Chandran, Aswin; Baeza, Jose Miguel Leon; Timofeeva, Vladislava; Nougue, Raphael; Takahashi, Shintaro; Ohno, Ryoma; Baceiredo, Antoine; Guerrero, Rene Segundo Rojas; Syroeshkin, Mikhail; Matsuo, Tsukasa; Saffon-Merceron, Nathalie; Kato, Tsuyoshi
    Phosphine-stabilized Pb(II) cations, generated by chloride abstraction from chloroplumbylene 1, readily react with Lewis bases (L) such as phosphines and amines to give the corresponding donor-acceptor complexes 3. These complexes 3 react with phenylacetlylene via alkyne insertion into the Pb-L bond to afford the corresponding vinylplumbylenes 4. Of particular interest, the stable complex 4-HNiPr2 (with a secondary amine) can be used as a hydroamination catalyst of phenylacetylene.
