Directed aromatic C-H functionalization of N-arylcarbamates and quinazolinones catalyzed by palladium nanoparticles supported on nitrogen-doped graphene

Pd nanoparticle-nitrogen doped reduced graphene oxide (Pd/N-RGO) nanohybrid was successfully utilized for the C-H-acyloxylation of N-arylcarbamates and the C-H halogenation of quinazolinones with N-halosuccinimides. The use of the catalyst was shown to be a highly efficient, less time-consuming and recyclable procedure for two different types of C-H functionalization; it was even better than Pd(OAc)2 as its homogeneous counterpart. Additionally, the effect of introducing nitrogen into the graphene lattice on the catalytic activities of palladium was evaluated by synthesizing Pd nanoparticles-reduced graphene oxide. The catalyst exhibited no significant palladium leaching; so, it was successfully recovered and reused in ten consecutive runs without any noticeable decrease in its catalytic activity.

Automated summary

Pd/N-RGO nanohybrid was used as a catalyst for efficient C-H acyloxylation and halogenation reactions. The introduction of nitrogen into the graphene lattice enhanced the catalytic activities of palladium, and the catalyst showed no significant palladium leaching, allowing for its successful recovery and reuse without any noticeable decrease in catalytic activity.
