Frustration and Cooperation in Bimetallic Complexes

Since we started as a group in 2017, we became very interested in combining the powerful chemistry of transition metals with the concept of frustrated Lewis pairs (FLPs). Our first aim was to obtain the first FLP where the two components are transition metals, a goal that we fulfilled with our most studied platform, a Au(I)/Pt(0) pair. Since then, we have tried to answer a number of fundamental questions:

How relevant are M···M interactions in bimetallic FLPs?
Does the interaction between bulky fragments need to be fully frustrated for enhanced reactivity?
How does the nature of the two metals influence reactivity?
How is the reactivity of soft/hard combinations vs hard/hard or soft/soft pairs?
Is the impact of sterics as important as in main group FLPs?
