A new protocol for the alkylation of aromaticamines has been described using alcohols in the presence of SmI2 as a catalyst with the generation of water as the sole byproduct. The reaction proceeds under MW conditions and selectively generates monoalkylated amines. This protocol features a broad substrate scope and good functional-group tolerance with moderate to high yields.

More efficient, cost effective and metal free DHP/TMSCl system for one pot reductive amination of aldehydes was developed. The method allows the efficient one pot synthesis of structurally diverse amines with Hantzsch ester as the hydrogen source in the presence of trimethylsilyl chloride as a catalyst in high to quantitative yields under mild conditions.
