A 1,1′-ferrocenyl phosphine-borane: Synthesis, structure and evaluation in Rh-catalyzed hydroformylation

Abstract

The new ambiphilic ligand Ph2P-(1,1′-ferrocenyl)-BMes 2, prepared by sequential lithiation/electrophilic trapping of 1,1′-dibromoferrocene, adopts a monomeric structure free of dative P → B and Fe → B interactions. This flexible phosphine-borane and the related o-phenylene bridged system have been evaluated in Rh-catalyzed hydroformylation. © 2010 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
