Pd-NHC (PEPPSI) Complexes: Synthetic Utility and Computational Studies into Their Reactivity

This review concentrates on the results obtained thus far in cross-coupling reactions utilising Pd-PEPPSI-IPr (pre)catalyst. Results from computational studies expose possible factors behind the high reactivity of this complex, as well as mechanistic details for the IPr-Pd-mediated alkyl-alkyl Negishi cross-coupling.
