An Ir‐catalyzed C(sp3)−H alkynylation of aliphatic ketones, aldehydes, and alcohols was achieved by using the corresponding oxime derivatives and a IrIII catalyst. This general reaction is selective towards primary C(sp3)−H bonds and can be used for the late‐stage C−H alkynylation of complex molecules.

Nitrogenation by direct functionalization of CHbonds represents an important strategy for constructing CN bonds. Rhodium(III)‐catalyzed direct amidation of unactivatedC(sp3)Hbonds is rare, especially under mild reaction conditions. Herein, a broad scope of C(sp3)Hbonds are amidated under rhodium catalysis in high efficiency using 3‐substituted 1,4,2‐dioxazol‐5‐ones as the amide source. The

Here we describe the development of a method for the Pd-catalyzed electrochemical acetoxylation of C–H bonds. The oxidation step of the catalytic cycle is probed through cyclic voltammetry and bulk electrolysis studies of a preformed palladacycle of 8-methylquinoline. A catalytic system for C–H acetoxylation is then developed and optimized with respect to the cell configuration, rate of oxidation,
