Increased selectivity in hydroformylation reactions using dendrimer based catalysts; a positive dendrimer effect

Abstract

Dendrimers based on polyhedral oligomeric silsesquioxanes (POSS) cores with 16 PPh2 arms give much higher linear selectivities (14∶1) than their small molecule analogues (3–4∶1) in the hydroformylation of oct-1-ene.
