Cooperativity between metal centers in homobimetallic PdII–NHC complexes: catalytic potential towards hydrodefluorination

Abstract

Among the several unsymmetrical bis-NHC derived distinct homo-bimetallic and mono-NHC supported Pd^II complexes studied here (1–5), the bimetallic complex 1 was noted to be the most effective catalyst for the challenging hydrodefluorination. The electron richness of the metal centers and the synergistic cooperation between the Pd^II centers (cooperativity index, ɑ = 8.67) have been recognized to be the deciding factor for its better activity.
