Pincer complexes are of interest in modern chemistry due to their high potential for catalytic applications. In this project, PNSi pincer hydride complexes with a labile COE ligand have been synthesized (complex 1 in scheme below). Its substitution reactions with phosphine and phosphite ligands have been investigated. By monitoring the Si-H and P-H coupling constants in the 1H NMR spectra in these substitution reactions, changes in hydride interactions with the metal center have been analyzed. The metal hydride intermediate is important in a number of related catalytic applications. The substitution products were characterized by single X-ray crystallography when possible.
