Palygorskite-anchored Pd complexes catalyze the coupling reactions of pyrimidin-2-yl sulfonates.

ABSTRACT: In this work, an anchored Pd complex (PGS-APTES-Pd(OAc)₂) was prepared via simple and green steps from the natural clay mineral palygorskite and was well characterized by XPS, XRD, IR, SEM, and EDX. This complex was further utilized as a fine catalyst for the C-C/C-N coupling reactions of pyrimidin-2-yl sulfonates. Subsequently, the cyclic utilization test indicated the high stability and sustainability of this PGS-APTES-Pd(OAc)₂ catalyst, and no activation was required in the recycling process, providing an applicable and reusable catalyst in organic synthesis.
