Phosphinoamide-supported early-late heterobimetallic complexes have been employed to activate small molecules via cooperative action of early and late transition metals. The bis(phosphinoamide) Zr/Co complexes have been an area of focus in recent years and have been shown to activate dihydrogen, catalytically semi-hydrogenate internal alkynes, and activate the <i>ortho</i> C-H bonds of pyridine derivatives. However, reports of bimetallic complexes containing the lighter group 4 congener Ti have been much more sporadic. While most of the chemistry of these bimetallic systems takes place at the Co center, the bis(phosphinoamide) Ti/Co complexes have differing reactivity from their Zr analogues, likely owing to differences in the electronic environment about the Co center.
