A series of Pd‐bis(NHC) (NHC = N‐heterocyclic carbene) complexes possessing various anions and substituents were used in the bisalkoxycarbonylation of olefins (α‐olefins and ethylene) to afford industrially useful succinic diesters in modest to good yields. The influence of different ligands and counteranions of the Pd complexes on their catalytic activity was assessed, and it was found that dimeric Pd–bis(NHC)Br was the best catalyst for the bisalkoxycarbonylation reactions. The structure of dimeric Pd–bis(NHC)Br was confirmed by X‐ray crystallographic analysis.
