Blue‐Light Irradiated Mn(0)‐Catalyzed Hydroxylation and C(<i>sp</i><sup>3</sup>)−H Functionalization of Unactivated Alkanes with C(<i>sp</i><sup>2</sup>)−H Bonds of Quinones for Alkylated Hydroxy Quinones and Parvaquone
Herein, a site-selective C−H alkylation of naphthoquinone with unactivatedalkanes using Mn2(CO)10 as a catalyst under blue-light (457 nm) irradiation without any utilization of external base, oxidant, and pre-functionalization is described. Using the presented methodology, the high-value-added compound parvaquone (a commercially available drug for treating theileriosis) and its derivatives can be
