Description |
The copper-catalyzed [3+2]azide–alkyne cycloaddition and the
Staudinger ligation are readily applicable and highly efficient for
the immobilization of cobalt Schiff base complexes onto polystyrene
resins. Stepwise synthesis of polymer-bound Schiff bases followed
by their subsequent complexation with metal ions were
successfully carried out. Direct covalent attachment of preformed
homogeneous cobalt Schiff base complexes to the resins was
also possible. The catalytic efficiency of the so-prepared poly-
ACHTUNGTRENUNGstyrene-bound cobalt Schiff bases was studied for the oxidation
of alcohols to carbonyl compounds using molecular oxygen as
oxidant. The immobilized complexes were highly efficient and
even more reactive than the corresponding homogenous analogues,
thus affording better yields of oxidized products within
shorter reaction times. The supported catalysts could easily be recovered
from the reaction mixture by simple filtration and reused
for subsequent experiments with consistent catalytic activity.
