Palladium allylic complexes with enantiopure bis(diamidophosphite) ligands bearing a cyclohexane-1,2-diamine skeleton as catalysts in the allylic substitution reaction

Allyl complexes with bisdiamidophosphite ligands resulted efficient precursors for the asymmetric allylic substitution reaction. The best performance was found with those with benzylcyclohexyldiamine terminal fragment and butanediol derived bridging fragment. The presence of the BPh4- anion enhances both activity and selectivity of the process.127
