Both qualitative molecular orbital theory and preliminary DFT studies suggest that a weak sigma-, strong pi-donor trans to the site of C-H activation at a d8 metal center should dramatically enhance the metal's ability to cleave C-H bonds. Terdentate 4-pyridonate-based pincer ligands hold tremendous promise as supports for C-H activation of some of the most challenging bonds. We will present our early attempts to synthesize these ligands and their platinum (II) complexes.
