The new ambiphilic ligand Ph2P–(1,10-ferrocenyl)–BMes2, prepared by sequential lithiation/electrophilic trapping of 1,10-dibromoferrocene, adopts a monomeric structure free of dative P-B and Fe-B interactions. This flexible phosphineborane and the related o-phenylene bridged system have been evaluated in Rh-catalyzed hydroformylation.
