Abstract
Herein, we report the synthesis of three indium complexes (1–3) supported by different chelating ligands (L1–L3). The indium metal complexes were characterized by using multinuclear NMR, and their solid-state structures were confirmed by single-crystal X-ray crystallography. The indium complex 1 (5 mol%) effectively reduced nitroarenes in the presence of phenylsilane and NaI. Nitroarenes containing different functionalities were reduced under standard conditions to give the corresponding amines in good yields.
