Abstract An iridium complex based on the unsymmetrical pyrenyl‐thiophene‐benzothiazole ligand was synthesized, and supported reduced graphene oxide successfully. The developed catalyst PTB‐Ir@rGO characterized through SEM, TEM, XPS, EDS. Meanwhile, we found that this heterogeneous had high catalytic activity in N‐alkylation of benzamide with alcohols via borrowing hydrogen strategy. Moreover, several control reactions preliminary mechanism explorations were carried out to study transformation. Finally, recycling experiment showed could be reused at least five times without a significant decrease activity.

A coordination polymer Ni-CIA has been designed, synthesized, and characterized via Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectrometry (XPS), energy-dispersive (EDS), thermal gravimetric analysis (TGA). The resulting reveals a slice layer stacked combination structure good stability. Importantly, this exhibited high catalytic activity for the synthesis of oxindole quinoline derivatives borrowing hydrogen dehydrogenation reactions. Meanwhile, several control reactions were carried out to investigate possible mechanisms transformation. Finally, results recycling experiment indicate that could be recovered reused at least five times.

Recently, metal-organic framework (MOF) and its derivatives showed great application potential in catalysis.ZIF-L-Co@phytate-iron (ZIF-L-Co@PA-Fe) heterogeneous MOF were synthesized by a facile surface engineering method.Phytic acid functionalized ZIF-L-Co (ZIF-L-Co@PA) was firstly prepared through organic ligand exchange of phytic (PA).Then, ZIF-L-Co@PA-Fe with unique heterostructure via coordination occurred between Fe 3 ＋ ligands.Benefiting from the greatly modify metal-ligand interactions, as-designed hybrids exhibited excellent catalytic activities toward hydrogen transfer reactions.2-Substituted benzoxazole successfully hydrogenative annulation o-nitrophenol alcohols catalyzed under solvent-free conditions.No additional additives, such as oxidants, reductants or bases required for this reaction.Moreover, complex reusability could be recycled up to five times without obvious decline activity.This work may provide effective guidance optimizing performance other series derivatives.
