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

thyl] complexes 4 via syn insertion of the pendant alkene into the Pd−N bond. Complexes 4 then undergo C−C bond-forming reductive elimination to yield N-aryl-2-benzylpyrrolidine derivatives 2. Kinetic studies indicate the rates of conversion of 3 to 4 and 4 to 2 are within 1 order of magnitude. The effects of phosphine ligand structure, alkene substitution, and the electronic properties of the Ar and
