Descrição geral
2-tert-Butyl-1,1,3,3-tetramethylguanidine (Barton′s base) is an excellent alternative to traditional inorganic bases for promoting the coupling reaction.
Aplicação
- Synthesis of dinaphthyl ethers: Barton′s base, which includes 2-tert-Butyl-1,1,3,3-tetramethylguanidine, was utilized to promote SNAr reactions for the synthesis of highly oxygenated dinaphthyl ethers, demonstrating its efficacy as a catalyst in complex organic synthesis processes (Wipf and Lynch, 2003).
Atenção

[reaction: see text] Electron-rich dinaphthyl ethers were synthesized by S(N)Ar reactions between naphthols and activated fluoronaphthalenes. 2-tert-Butyl-1,1,3,3-tetramethylguanidine (Barton's base) was found to be an excellent, mild alternative to traditional inorganic bases for promoting the coupling reaction.
