Abstract New Pd(II) complex, trans-[PdCl2L2] (1) (L = N-carbamothioylthiophene-2-carboxamide), was prepared and characterized. Its heterogeneous counterpart, trans-[PdCl2(L-SNPs)2] (2) (L-SNPs = ligand immobilized on silica nanoparticles), was also prepared through covalent modification of the ligand using silica nanoparticles and characterized. Both 1 and 2 were exploited for their catalytic activity towards condensation of phenylacetylene with aryl halides. The complexes exhibited good activity when aryl halide bears I- or Br- group. Further, catalyst 2 can be reused for four cycles.

Pd(II)-酰基硫脲配合物及其固定化对应物催化苯乙炔与芳基卤化物的缩合

摘要 制备并表征了新的 Pd(II) 配合物，trans-[PdCl2L2] (1)（L = N-carbamothioylthiophene-2-carboxamide）。它的异质对应物，反式-[PdCl2(L-SNPs)2] (2)（L-SNPs = 固定在二氧化硅纳米颗粒上的配体），也是通过使用二氧化硅纳米颗粒对配体进行共价修饰来制备并表征的。1 和 2 都被利用对苯乙炔与芳基卤化物的缩合的催化活性。当芳基卤带有I-或Br-基团时，配合物表现出良好的活性。此外，催化剂2可以重复使用四个循环。
