explored as catalysts for the hydrogenborrowing reactions of amines and alcohols. Bidentate carbene-triazole ligands were readily synthesized via “click” reactions which allowed a diversity of ligand backbones to be accessed. The catalytic transformations are highly efficient, able to reach completion in under 6 h, and promote C–N bond formation across a range of primary alcohol and amine substrates. Moreover

A New facile and general synthesis of alkylanilines by one-pot reductive alkylation of nitroarenes is reported. This method is based on the “in situ” reduction by hydrides (LiAlH4 or NaBH4) in the presence of catalytic amounts of PdC, of nitronate adducts arising from the conjugate addition of Grignard reagents to mononitroarenes. LiAlH4 showed to be a more efficient but less selective reducing agent
