A transition-metal-assisted oxidative C(sp(3))-H/N-H cross-coupling reaction of N-alkoxyamides with aliphatic hydrocarbons is described. During the reaction, nitrogen radicals were generated from the oxidation of N-alkoxyamides. Experiments and DFT calculations revealed that transition-metal catalyst could lower the reactivity of the generated nitrogen radical by the coordination of the transition metal, which allowed the selective radical/radical cross-coupling with the transient sp(3) carbon radical to construct C(sp(3))--N bonds. Various C(sp(3))-H bonds could be transformed into C(sp(3))-N bonds through this radical amidation strategy.

The azide anion as an energy acceptor and an electron donor has been introduced into a metal-viologen compound to form a 2D layered viologen-based trifunctional material, which exhibits the rare discolored function of reversible photochromism and thermochromism. Interestingly, its fluorescence can be switched by visible light irradiation and heating in air.

M2 macrophages attenuate sepsis-induced AKI, presumably by upregulating IL-10 expression and suppressing TNF-α secretion.
