Multifunctional and robust covalent organic framework–nanoparticle hybrids

Highly stable COF supported Pd(0) and Pd( ii ) nanoparticles ( i.e. Pd(0)@Tppa-1 and Pd(ii)@TpPa-1 ) have been synthesized. Pd(0)@TpPa-1 serves as a robust and efficient heterogeneous catalyst for copper free Sonogashira and Heck coupling reactions under basic conditions, whereas Pd(ii)@TpPa-1 satisfactorily catalyzes intramolecular oxidative biaryl synthesis under acidic conditions.
