• The synthesis of cationic mono oxo MoIV PNP pincer complexes of the type [Mo(PNPMe‐iPr)(O)X]+ (X = I, Br) from [Mo(PNPMe‐iPr)(CO)X2] is described. These compounds are coordinatively unsaturated and feature a strong Mo≡O triple bond. The formation of these complexes proceeds via cationic 14e intermediates [Mo(PNPMe‐iPr)(CO)X]+ and requires both molecular oxygen and water. ESI MS measurements with 18O labeled water (H218O) and molecular oxygen (18O2) indicates that water plays a crucial role in the formation of the Mo≡O bond. A plausible mechanism based on DFT calculations is provided. The X‐ray structure of [Mo(PNPMe‐iPr)(O)I]SbF6 is presented. The synthesis of cationic mono oxo MoIV PNP pincer complexes of the type [Mo(PNPMe‐iPr)(O)X]+ (X = I, Br) is described. These compounds are coordinatively unsaturated and feature a strong Mo≡O triple bond. Their formation requires cooperation between molecular oxygen and water.
