Core-insertion of palladium in naphthalenediimides: Opto-electronic properties, structural insights and coupling studies

Synthesis and isolation of palladium inserted functional π-scaffold is considered a major challenge due to its high instability and reactivity towards molecular oxygen. Herein, we report two σ-bonded compounds (1 and 2) between Naphthalenediimide (NDI) and palladium triphenylphosphine. Both these core-substituted NDI-palladium compounds have been characterized as NDI-{Pd(PPh3)2Br}2 having two Pd(PPh3)2 (1) and (C3H7)NH-NDI-Pd(PPh3)2Br having one...
