Key Points

• This research aims to explore the C-H alkylation of fluorenes using copper-based complexes.
• Utilized o-phenylenebridged bis-azopyridyl complexes of copper as catalysts.
• Conducted reactions under controlled conditions to assess the alkylation process.
• Analyzed products to identify successful alkylation outcomes.
• Demonstrated significant C-H alkylation of fluorenes using the specified copper complexes.
• Showed that noninnocent ligands enhance catalytic activity compared to traditional ligands.
• Achieved a range of alkylated fluorenes with high selectivity and yield.
