Dendrimers based on polyhedral oligomeric silsesquioxanes (POSS) cores with 16 PPh 2 arms give much higher linear selectivities (14+1) than their small molecule analogues (3-4+1) in the hydroformylation of oct-1-ene.

Novel transition metal catalysts based on oligonucleotides can be easily obtained by functionalization of 5-iodouridine with phosphine ligands, resulting in good asymmetric induction in palladium catalyzed allylic nucleophilic substitution.
