N2 - Kinetic parameters for the [5,6]-to [6,6]-[Li+@PCBM]TFSI- transformation were determined experimentally, revealing a ca. 700-fold faster reaction rate at 423 K than empty PCBM and a 57.4 kJ mol-1 lower activation energy. The encapsulated Li+ can be considered as solvation-free Li+, forming a 1:1 complex with the substrate.
