The research focuses on the synthesis and investigation of Platinum NCN-pincer complexes derived from 1,3-bis(imino)benzenes as catalysts for carbon-carbon bond formation. The purpose of this study was to develop a direct route to these complexes, which are of significant interest due to their potential applications in catalysis and organometallic materials. The researchers successfully synthesized a range of platinum NCN-pincer complexes by reacting 1,3-bis(imino)benzenes with K2PtCl4 in glacial acetic acid, yielding the desired complexes in moderate to good yields. The study also explored the activation of these complexes through chloride abstraction, resulting in water-coordinated adducts with either tetrafluoroborate or triflate counterions. The triflate salt of the complex was found to display moderate activity as a catalyst for the Michael and Diels-Alder reactions involving nitrile substrates.
