Transition-Metal-Functionalized PAMAM Dendrimers Encapsulated in PPX Tubes as Reusable Catalysts
Composite
nanofibers of polyurethane and catalytically active Pd-
or Cu-functionalized poly(amido amine) dendrimers were electrospun
and subsequently coated with poly(<i>p</i>-xylylene) by
the chemical vapor deposition. After removal of the inner polyurethane
template matrix, the dendrimers remained encapsulated inside the confinement
and the leaching behavior of the caged dendritic catalysts was studied.
The tube system was successfully used as a readily reusable tea bag
type catalyst for Suzuki–Miyaura couplings and alkyne/azide
