Copper(I)-Mediated Divergent Synthesis of Pyrroquinone Derivatives and 2‑Halo-3-amino-1,4-quinones
A divergent transformation of 2-amino-1,4-quinones for the synthesis of pyrroquinone derivatives and 2-halo-3-amino-1,4-quinones was disclosed. The mechanistic study showed that both the tandem cyclization and halogenation involved a Cu(I)-catalyzed ...

Radical Benzylation of Quinones via C–H Abstraction
, 2019 Herein we report the development of radical benzylation reactions of quinones using Selectfluor and catalytic Ag(I) initiators. The reaction is believed to proceed via a C–H abstraction mechanism after Ag(I)-mediated reduction of Selectfluor.
