Abstract

New acyclic aminophosphites (RO)2POCH2CH2NMe2 (PN) (R=Et, Pri, or adamantyl) characterized by various steric requirements of the phosphorus center were synthesized. The reactions of the aminophosphites with Pd(COD)Cl2 (COD is 1,5-cyclooctadiene) and [Rh(CO)2Cl]2 afforded the stable chelate mononuclear complexes PdCl2(PN) and RhClCO(PN), respectively. The structures of the resulting compounds were established by1H,13C, and31P NMR and IR spectroscopy, X-ray diffraction analysis, laser and plasma desorption mass spectrometry, X-ray photoelectron spectroscopy, and sedimentation analysis.
