transformations in organic synthesis. Herein, we report an unprecedented hydrodeoxygenative coupling of aromatic aldehydes to form bibenzyls by a N2-derived tetranuclear titanium imide/hydride complex [(Cp′Ti)4(μ3-NH)2(μ-H)4] (1; Cp′ = C5Me4SiMe3). Further reactions with the corresponding aldehydes under air afford hydrobenzamides together with a titanium oxo complex. Both hydride and imide ligands play an important

Herein, we present a CuI-dimer, [CuIPh2PC6H4C(O)NC6H4PPh2-o}]2, which catalyzed directC(sp3)–H homocoupling of benzyl and cycloalkane derivatives with excellent yields and regio-selectivity. The method is very simple and tolerates various functionalities. Synergistic metal–ligand cooperativity was observed in Cu–N bond cleavage and protonation of nitrogen, and facilitates a bifunctional pathway,
