Résumé

Fréchet-type dendrons containing a chelating N,P-iminophosphine entity at the focal point were synthesized by reacting an N,P-iminophosphine Schiff base with the appropriate bromido-Fréchet dendron (G0, G1 or G2) via a Williamson-ether reaction. Neutral Rh(I) organometallic dendrons were synthesized by reacting the N,P-iminophosphine dendron with [Rh(μ-Cl)(CO)2]2. The ligands and complexes were characterised using NMR and IR spectroscopy, mass spectrometry, elemental analysis and the G0 analogue was characterised using single-crystal X-ray diffraction. All complexes were evaluated as catalyst precursors for the hydroformylation of 1-octene.
