Enroute sustainability: metal free C-H bond functionalisation

Area of Science:

• Organic Chemistry
• Sustainable Chemistry

Background:

• C-H functionalization involves activating and transforming carbon-hydrogen bonds into new carbon-carbon or carbon-heteroatom bonds.
• Transition-metal catalysis is atom-economical but often requires activated precursors, posing challenges for large-scale synthesis.

Purpose of the Study:

• To provide a comprehensive overview of recent advancements in metal-free C-H functionalization.
• To highlight green, sustainable, and cost-effective synthetic strategies for C-H bond transformation.

Main Methods:

• Review of recent literature on metal-free C-H functionalization reactions.
• Focus on catalytic approaches that avoid transition metals.

Main Results:

• Emergence of metal-free strategies as a viable alternative to metal catalysis.
• Development of greener, cheaper, and non-toxic methods for C-H bond functionalization.

Conclusions:

• Metal-free C-H functionalization is a rapidly growing field driven by sustainability and cost-efficiency.
• These approaches offer significant advantages over traditional metal-catalyzed methods for various synthetic applications.
