Synthesis and Comparative Studies of Cyclopalladated Complexes With Ortho C‒H Activation of Aromatic Rings Bearing Electron Donating and Electron Withdrawing Groups

The present study was undertaken to throw more light on the cyclopalladation mechanism. The reactivity of Schiff base ligands {N - (4­methoxy benzylidene) ­4-methoxyaniline (1) and N - (4­nitro benzylidene) ­4­methoxyaniline (2)} by interaction with palladium (II) acetate is allowed to the isolation of different complexes (1a–f) and (2a–f). All the newly synthesized compounds are characterized using elemental analysis, IR, UV-VIS, 1HNMR and mass spectral tools as well as TGA.
