Methods for selective C–H bond functionalization have provided chemists with versatile and powerful toolboxes for synthesis, such as the late-stage modification of a lead compound without the need for lengthy de novo synthesis. Cleavage of anC–H bond via hydrogen atom transfer (HAT) is particula...
This reaction complements ‘C–H activation’ strategies that convert inert C–H bonds into C–metal bonds prior to C–C bond formation. Instead, this reaction exploits an inverted sequence and promotes C–C bond formation prior to deprotonation. These studies provide an opportunity to develop ...

Complex 1 also promotes the B–H bond activation of pinacolborane (HBpin) and catecholborane (HBcat). The reactions initially give the trans-dihydride derivatives RhH2(BR2){xant(PiPr2)2} (BR2 = Bpin (7), Bcat (8)), which lose H2 to afford the square-planar Rh(BR2){xant(PiPr2)...

In this paper, we report an eco-friendly approach for the C(sp2)–H bond selenylation of imidazopyridines and other N-heteroarenes as well as simple arenes at ambient temperature. This new protocol consists of the reaction between (N-hetero)-arenes and t
