General description

2-tert-Butyl-1,1,3,3-tetramethylguanidine (Barton′s base) is an excellent alternative to traditional inorganic bases for promoting the coupling reaction.

Application

  • 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).

Disclaimer

Remark on appearance: Material may form precipitate on storage. The precipitate may easily be separated by filtration.
