New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 2892-51-5, Name is 3,4-Dihydroxy-3-cyclobutene-1,2-dione, molecular formula is C4H2O4. In an article, author is Sutar, Suraj M.,once mentioned of 2892-51-5, Category: benzoxazole.
A green C-H bond activation of azole based bio-pertinent substrates such as benzoxazole, benzothiazole, benzimidazole are accomplished using readily prepared 1-aryltriazenes as arylating agent. Under an optimized condition employing Pd(OAc)(2)and CuI in either hydrophilic [Bmim][BF4] or hydrophobic [Bmim][PF6] IL medium with [BMIM(SO3H)][OTf] as a promoter, these arylation reactions proceeded smoothly to afford 2-aryl substituted azoles in acceptable to better yields besides noticeable functional group tolerance. The prospective for recovery and re-use of ionic liquid solvent is demonstrated.
