um photocatalyst, N-BAP, with high photoredox abilities and visible-light absorption was designed and prepared in one step. Under visible-light irradiation, N-BAP promoted the four-electron reduction of esters in the presence of ammonium oxalate as a “traceless reductant” to generate carbinol anion intermediates that underwent protonation with water to give the corresponding alcohols. The resulting
一步设计并制备了一种具有高光氧化还原能力和可见光吸收能力的新型二氮杂苯并苊光催化剂N- BAP 。在可见光照射下, N- BAP在草酸铵作为“无痕还原剂”存在下促进酯的四电子还原,生成甲醇阴离子中间体,该中间体与水发生质子化,得到相应的醇。所得的甲醇阴离子在光催化条件下也表现出亲核反应性,与第二个羰基化合物进行 1,2-加成,得到不对称的 1,2-二醇。
