This study introduces a new method for distal C-H activation using palladium migration, facilitated by a transient directing group. This approach enables efficient heteroannular C-H functionalization of ferrocenecarboxaldehydes.
Area of Science:
- Organometallic Chemistry
- Catalysis
- Synthetic Organic Chemistry
Background:
- Distal C-H activation is crucial for complex molecule synthesis.
- Palladium migration on stacked molecules is a key strategy for C-H activation.
- Transient directing groups (TDGs) can enable palladacycle formation for migration.
Purpose of the Study:
- To develop a method for distal C-H functionalization using heteroannular palladium migration.
- To investigate the role of monodentate TDGs and ligands in fine-tuning palladium migration.
- To demonstrate the efficacy of this method on ferrocenecarboxaldehydes.
Main Methods:
- Utilized a monodentate transient directing group (TDG) and an additional ligand.
- Investigated palladium migration pathways through control experiments.
- Applied the developed method to synthesize functionalized ferrocenecarboxaldehydes.
Main Results:
- Successfully achieved distal heteroannular C-H functionalization of ferrocenecarboxaldehydes.
- Demonstrated 23 examples of this novel functionalization.
- Showcased the fine-tuning of palladium migration via TDG and ligand selection.
Conclusions:
- Monodentate TDG-enabled heteroannular palladium migration is a viable strategy for distal C-H activation.
- This method offers a new route for functionalizing ferrocenecarboxaldehydes.
- The approach provides an alternative to template-designed C-H activation strategies.
