is heterogeneous in nature (Figure S11). The EDX analysis of
the filtrate shows that absence of Zn metal in the solution
(Figure S12). To check the recyclability we have performed the
catalysis reaction and result showed that compound 1 maintains
its catalytic activity through multiple cycles (Figure S13).

In summary, through the incorporation of a urea-based
HBD catalyst into the Zn-based framework, we have produced
an efficient, and robust heterogeneous catalyst for F-C reactions
between unsubstituted indole and -nitroalkenes. Here we have
demonstrated that through the incorporation of the self-
associative HBD organocatalyst into a MOF, one can “turn on”
novel catalytic activity not seen in the free organocatalyst. The
approach of hydrogen-bonding catalysis in a MOF has gained
interest very recently. This is cheap and inexpensive catalyst
that mitigate the cost of the reaction. This newly synthesized
MOF with larger pore can accomodate larger substares for F-C
reaction which is inaccessible by other reported HBD based
MOFs.
