Ligand\u2010redistribution energetics further indicate that Cp\u2010mediated routes do not provide a thermodynamic driving force toward the homoleptic complex and, together with known temperature constraints for borane anions and borane\u2010ring rearrangements, support a Cp\u2010free, temporally decoupled capture\u2500then\u2500anneal strategy.
