A series of air‐stable, phosphine‐free areneruthenium (II)–NNN pincercomplexes (RuL, RuL1, RuL2 and RuL3) have been synthesized and characterized by spectroscopic and single‐crystal X‐ray analysis. Further, areneruthenium (II)–NNN pincercomplexes have been used as catalyst for hydrogenation of nitroaromatics into aniline in the presence of NaBH4 at room temperature. The catalytic process suggested
