The development of metalated porous
organic polymers (POPs) is
vital for producing recyclable heterogeneous catalytic systems that
are useful for real-world applications. Herein, we report the synthesis,
characterization, and catalytic desulfurization properties of an olefin-linked
POP containing Ni-doped dehydrobenzoannulene (DBA) units. We show
that a Ni-DBA-TMT-POP can be used to remove sulfur from dibenzothiophenes
(DBTs) and benzothiophenes (BTs) in the presence of Grignard reagents
and phosphine ligands. The Ni-DBA-TMT-POP catalytic system exhibits
great recyclability and respectable yields. This work highlights a
rare example of utilizing a Ni-doped DBA-POP for the desulfurization
of refractory sulfur compounds that are commonly found in sour crude
oil.
