Abstract
The chloro-bridged dimer [Pd(μ-Cl)(C6H4CH2NH2-κ2-C,N)]2 reacts with PPh2Et, P(p-tolyl)3, AsPh3, piper (piper = C5H10N) and Py in dichloromethane at room temperature for 24 h in a one-to-two molar ratio and undergoing bridge-splitting reactions to give [PdCl(C6H4CH2NH2–κ2-C,N)L] (L = PPh2Et (1a), P(p-tolyl)3 (1b), AsPh3 (1c), piper (1d), C6H4CH2NH2 (3e) and Py (1f)). Complex 1f in THF at room temperature reacts with a stoichiometric amount of TlTfO (thallium triflate, TfO=CF3SO3) and Py (molar ratio 1 : 1 : 1) to afford [Pd(C6H4CH2NH2)(Py)2]TfO (2). Infrared and NMR spectroscopies allow unambiguous characterization of these products.
