En Route to Intermolecular Cross-Dehydrogenative Coupling Reactions

Area of Science:

• Synthetic Organic Chemistry
• Green Chemistry
• Catalysis

Background:

• Cross-coupling reactions involving two C-H bonds are increasingly vital in modern synthesis.
• Cross-dehydrogenative coupling (CDC) enables direct bond formation from C-H and Z-H bonds under oxidative conditions.
• Existing categorizations of C-C bond-forming CDC reactions are disorganized due to their diversity.

Purpose of the Study:

• To present a contemporary categorization of C-C bond-forming CDC reactions.
• To organize these reactions based on C-H activation strategies.
• To aid synthetic chemists in designing novel CDC reactions.

Main Methods:

• Review and analysis of existing literature on CDC reactions.
• Development of a novel categorization framework based on C-H activation mechanisms.
• Discussion of the implications of this categorization for future research.

Main Results:

• A new, mechanism-based categorization of C-C bond-forming CDC reactions is proposed.
• This framework addresses the current disarray in classifying diverse CDC methodologies.
• The categorization provides insights into C-H activation strategies.

Conclusions:

• The proposed categorization offers a clearer understanding of C-C bond-forming CDC reactions.
• This framework is expected to stimulate the design of new and efficient CDC methodologies.
• It serves as a valuable resource for synthetic chemists in the field.
