The development of environmentally friendly heterogeneous catalysts for organic reactions in water is becoming of growing importance for the development of sustainable processes. In this work, a porous organic polymer-supported palladium catalyst (Pd@UPOP-1) was successfully fabricated from 3,3-diaminobenzidine and methylenediphenyl diisocyanate through a facile urea-forming condensation reaction. The structure and composition of the catalyst were characterized using several physicochemical methods. Pd@UPOP-1 was found to possess good porous structure and excellent amphiphilicity. Under mild reaction conditions, the catalyst showed excellent catalytic activity and good substrate compatibility for the Suzuki-Miyaura coupling reaction of aryl bromides, as well as the hydroxycarbonylation reaction of aryl iodides. In addition, the catalyst could be used for several consecutive recycles in both cases.
