Popis: Imine-based microporous covalent organic frameworks, TATAE were synthesized from condensation of 4,4′,4“-(1,3,5-triazine-2,4,6-triyl)tribenzaldehyde and 1,4-diaminobenzene, followed by Pd(OAc)2 was incorporated on TATAE (Pd/TATAE). The as-synthesized Pd/TATAE was thoroughly characterized by Fourier Transform-Infrared Spectroscopy, 13C CP-MAS solid state nuclear magnetic resonance, powder X-ray diffraction, X-ray photoelectron spectroscopy, thermo gravimetric analysis, scanning electron microscopy and transmission electron microscopy. The Pd/TATAE was employed as a solid catalyst for Suzuki-Miyaura coupling reactions in an environmentally benign water medium at room temperature, which exhibited a good catalytic activity with excellent yield. In addition, the heterogeneous nature of the catalyst was checked by Shelton test, this catalyst can be recycled more than four times with only a minor loss of its catalytic activity.
