    Deciphering the Role of Internal Donors in Shaping Heterogeneous Ziegler–Natta Catalysts Based on Nonempirical Structural Determination حسب João Marcos da Silveira (17871851)

    منشور في 2024
    "…The addition of internal donors (IDs) to the heterogeneous Ziegler–Natta catalyst for propylene polymerization is fundamental to obtain highly isotactic polypropylene, but its role in shaping the stereospecific structure of the catalyst is still not comprehended. …"

    Oxidative Nickel-Catalyzed <i>ortho</i>-C–H Amination of (Iso)quinolines with Alicyclic Amines Directed by a Sacrificial <i>N</i>‑Oxide Group حسب Weiqi Zhu (17845973)

    منشور في 2024
    "…Transition metal (TM)-catalyzed direct amination of C–H bonds on free or fused pyridine (Py) rings with free amines still remains scarce because amines and the Py ring tend to adopt a nonproductive N-bound coordination with many TMs, leading to a significant decrease of catalytic reactivity. We herein disclose a nickel-catalyzed and a sacrificial <i>N</i>-oxide group directed oxidative coupling of (iso)quinolyl C–H bonds and alicyclic amines, which furnishes bioimportant amino(iso)quinolines efficiently and selectively in a single step. …"
