| Abstract |
The synthesis of cationic mono oxo Mo-IV PNP pincer complexes of the type [Mo(PNPMe-iPr)(O)X](+) (X = I, Br) from [Mo(PNPMe-iPr)(CO)X-2] is described. These compounds are coordinatively unsaturated and feature a strong MoO 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 O-18 labeled water ((H2O)-O-18) and molecular oxygen (O-18(2)) indicates that water plays a crucial role in the formation of the MoO bond. A plausible mechanism based on DFT calculations is provided. The X-ray structure of [Mo(PNPMe-iPr)(O)I]SbF6 is presented. |
