The selective hydrogenation of cyclic and acyclicdienes to monoolefins occurs under very mild conditions, in the presence of silica-supported PAMAM-Pd complexes. The activity and selectivity of this reaction is sensitive to the dendrimer structure. These dendritic complexes display excellent recycle properties, retaining activity for up to eight recycles.

The relative reactivity series for the epoxidation of alkenes by dimethyldioxirane showed the reaction to be unexpectedly sensitive to steric factors; compounds were ∼8 times as reactive as the isomers.
