A gold complex containing 2,7‐bis(mesitylimidazolylidenyl)naphthyridine ( NHC‐NP ) has been synthesized. Thus, reaction of [{Ag 3 ( NHC‐NP ) 2 }(PF 6 ) 3 ] with [Au(Me 2 S)Cl] provided an unusual digold complex bridged by two NHC‐NP , forming a 20‐membered dinuclear metallacycle [{Au 2 ( NHC‐NP ) 2 Cl 2 }(PF 6 ) 2 ] ( 2 ) in high yield. This complex was characterized by spectroscopic and elemental analysis. This gold complex is active for the hydrolysis of 2,2,5‐trimethyl‐1,3‐dioxane‐5‐methanol and can be recycled without losing the activity.
