Synthesis of group six PCP complexes via oxidative addition under solvothermal conditions

Synthetic reactions should be fast and atom efficient and therefore often transition metals are used as catalyst. Pincer complexes are playing a significant role due to their stability and the possibilities to modify them.
In this work the synthesis of a PCP Pincer ligand with methylene linkers and Br located at the benzene ring between the linkers, as well as its complexes with the group six carbonyl precursors, will be reported [1]. One of the benefits of the new ligand system is that agostic interactions can be avoided [2]. The group six metals PCP pincer complexes were successful synthesised with the so-called solvothermal method and characterised (Figure 1) [3]. Furthermore the redox properties of the different complexes were investigated.
