one-pot two-step reductive coupling between acetyl naphthalenederivatives, tosylhydrazide, and arylboronic acids, affording substituted 1(or 2)-(1-phenylethyl)naphthalenes in moderate-to-excellent yields, was reported. Notably, solvent played a crucial role in the coupling of 1-acetyl naphthalenederivatives (toluene) or 2-acetyl naphthalenederivatives (1,4-dioxane) as starting materials. Meanwhile,

A novel copper-catalyzedarylation of benzylic C-H bonds with nucleophilic arylboronic acids has been developed that provides an efficient way to synthesize various 1,1-diarylalkanes with a broad substrate scope and excellent functional group compatibility. The reactions occur at room temperature using alkylarenes as the limiting reagents, which allows access to the arylation of the more valuable and
