The catalytic performance of H-MOP-CA-Ag is comparable or
superior to the recent Ag-based heterogeneous catalysts.[19c–e,20]
For example, under similar reaction conditions (room temper-
ature and 10 h), 10 mol% Ag-sulfonated resin showed a 91%
yield of cyclic carbonate with 1 atm CO2 and 2-methyl-3-butyn-
2-ol.[19e] The excellent catalytic performance of H-MOP-CA-Ag is
attributable to its efficient distribution of Ag ions over the
hollow MOP support.[11,21] When the same amounts of H-MOP-1-
Ag and H-MOP-2-Ag were used under the same reaction
conditions, the cyclic carbonates were formed with yields of 35
and 58%, respectively. When 1-ethynyl-cyclohexan-1-ol was
used with 2 mol% Ag of H-MOP-CA-Ag, a 74% yield of cyclic
carbonate was obtained.

The H-MOP-CA-Ag could be reused in the second and third
runs, showing 90 and 88% yields of cyclic carbonates,
respectively, 1.6% Ag leaching after third run, and the complete
retention of the original morphologies (Figure 6e and S9 in the
SI).

In conclusion, this work shows that H-MOP-A can be
synthesized through acyl Sonogashira-Hagihara coupling of
tetra(4-ethynylphenyl)methane with terephthaloyl chloride at
room temperature. The internal alkynes in the H-MOP-A showed
enhanced chemical activities and a very sharp IR peak at
2194 cmÀ 1, which could be utilized in the monitoring of its
main chain PSM based on nonradical thiol-yne reaction. The
resultant H-MOP-CA bearing propionic acid groups could be
utilized as a Ag(I) support. The resultant catalytic system
showed excellent performance in the CO2 fixation with
propargyl alcohols to α-alkylidene cyclic carbonates. We believe
that chemical structures of H-MOP-A can be further diversified
through a pre-designed building block approach and tailored
PSM.
