Abstract:A hollow catalyst bearing N-heterocyclic
carbene
(NHC)–Fe species was synthesized using a hollow microporous
organic polymer (HMOP) as a template. In the presence of HMOP, the
Friedel–Crafts reaction of 1,3,5-tri(bromomethyl)benzene induced
the loading of hypercrosslinked polymer (HCP) onto HMOP. The resultant
HMOP@HCP material bearing benzyl bromide groups could be further modified
with N-methylimidazole to form HMOP@HCP bearing imidazolium
salt (HMOP@HCP-Im). The use of KO
