    Metal‐free fast azidation by using tetrabutylammonium azide : effective synthesis of alkyl azides and well‐defined azido‐end polymethacrylates by Wang, Chen-Gang, Chong, Amerlyn Ming Liing, Lu, Yunpeng, Liu, Xu, Goto, Atsushi

    Published 2020
    “…Notably, the combination of organocatalyzed living (or reversible deactivation) radical polymerization and BNN3 azidation enabled the metal‐free synthesis of azido‐end polymethacrylates, including single‐azido‐end and multi‐azido‐end functional homopolymers and block copolymers. The rapid and quantitative reaction without the requirement for a large excess of BNN3, metal‐free and polar‐solvent‐free nature, and broad polymer scope are attractive features of this azidation.…”
