A dehydroxylative Csp3-N coupling reaction assisted by triphenylphosphine has been developed through electrochemicaloxidation. The reaction proceeds via anodic oxidation of triphenylphosphine to generate its corresponding radical cation, followed by reacting with hydroxyl groups to form alkoxy triphenylphosphonium ions, which are trapped by azoles or amides to construct C-N bonds. This method provides

general approach for the synthesis of allylated and benzylated pyrazoles. An electron-withdrawing substituent, such as nitro, chloro, and ester groups, at C4 renders the Lewis basic nitrogen atom to be less basic and the C–H bond more acidic than the ones of the parent ring, enabling Pd-catalyzed C–H allylation and benzylation reactions of pyrazoles. The new method expanding the scope of the C–H functionalization

Facile homo‐coupling of terminalalkynes, which generates conjugated diynes, is an undesired pathway in the development of transition‐metal‐catalyzed oxidative C–H functionalization of (hetero)arenes with terminalalkynes. By incorporating this process into a catalytic cycle, we achieved regio‐ and stereoselective hydroarylation of nitropyrazoles with the resulting 1,3‐diynes. A simple change in the
