MOF-based Pd catalysts: a controllable and efficient platform towards cyclization reactions of isonitriles

Abstract: Catalytic efficiency is crucial to the reaction system and intrinsically related to the physical and chemical conditions. One of the challenges to enhance the catalytic efficiency has been the limited...

“…On the basis of these experimental results and previous works, 33,42 a plausible mechanism for the Zr-BTB-Bpy-Pd-catalyzed cyclization of isonitriles with N -acyl- o -alkynylanilines for 2-aminoquinolines was proposed (Scheme 2). Initially, the Pd( ii ) species of Zr-BTB-Bpy-Pd coordinates with 1a to generate intermediate I that can be confirmed by the results of FT-IR spectra of 1a /Zr-BTB-Bpy-Pd.…”

“…42 To improve the catalyst recyclability, a heterogeneous 3D MOF based Pd( ii ) catalyst Pd-UiO-67-Bpy was recently explored for the above reaction by our group. 33 Compared to the homogeneous Pd(OAc) 2 systems, in addition to markedly increased turnover numbers (TONs), the 3D MOF based Pd( ii ) catalyst exhibited better controllability of Pd( ii ) species in the catalytic process and the self-healing of the catalyst originated from the free uncoordinated Bpy moieties in the MOF. With the well-prepared Zr-BTB-Bpy-Pd in hand, herein we also evaluated its catalytic performance using the cyclization reaction of N -acyl- o -alkynylanilines with isonitriles.…”

“…Meanwhile, the potential metal sites could be well reserved without being occupied in solvothermal reactions. [108][109][110][111][112][113][114] Fig. 6 shows some of the typical organic ligands used for constructing MOFs for metalation.…”
