Abstract
Starting from mononitrotetrakis(iodophenyl)methane
as monomer, we report the preparation of the first
pre-functionalised porous aromatic frameworks (PAFs) and
their application as supports for organometallic catalysts.
Neutral coordinate imino-pyridine Schiff base (PAF-NPy) or
chiral bis-amino (PAF-NPro) ligands were obtained by postsynthetic
treatment of PAF-NH2 and treated with copper(I)
or rhodium(I) to yield the corresponding supported transition-
metal catalysts. The as-prepared PAF-NN-M catalysts exhibited
activity and selectivity similar to that of the corresponding
homogeneous catalysts and were easily removed
from reaction media and recycled without loss of activity or
selectivity.
