strategy was utilized to prepare Pd(II) organometallic catalysts immobilized on
the triphenylphosphine-functionalized KAPs(Ph-PPh

) (Fig.

). The porous
structure provides the high dispersion of active Pd sites. In addition, heterogene-
ous porous structure also improved the diffusion of organic reactant molecules.
Therefore, the resulted catalyst exhibited excellent activity and selectivity for the
Suzuki-Miyaura cross-coupling reaction of aryl chlorides even under mild condi-
tions and aqueous reaction media. KAPs(Ph-PPh
3
)-Pd could satisfy the demand
on an industrial scale owing to various advantages, including nontoxic aqueous
media, mild reaction conditions (80 °C), stability of the catalyst, and the facile
