Publication date: Available online 4 July 2019Source: Journal of Organometallic ChemistryAuthor(s): Nobuhiro Takeda, Rin Oma, Yuki Kogure, Fumiaki Sakakibara, Yusuke Tanaka, Masafumi UnnoAbstractDimethylpalladium complex bearing PS3-type tripodal tetradentate ligand, [PdMe2{P(C6H4-2-S-i-Pr)3}], was synthesized by the reaction of [PdCl{P(C6H4-2-S-i-Pr)3}]X (X = Cl, BF4) with methyllithium (Br free). The dimethylpalladium complex reacted with an equimolar amounts of HCl to give the corresponding chloromethylpalladium complex, [PdClMe{P(C6H4-2-S-i-Pr)3}], while the similar reaction using 2 M amounts of HCl afforded the dichloropalladium complex, [PdCl{P(C6H4-2-S-i-Pr)3}]Cl. The detailed structures of the complexes were revealed by X-ray crystallography and variable temperature 1H NMR studies.Graphical abstract
