A new dibrominated 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) is reported as a new metal-free photocatalyst. This BODIPY showed similar optoelectronic, electrochemical, and performance properties to those of Ru(bpy)3Cl2, one of the most common photocatalysts in a known radical–ionic transformation, such as the formation of 1,4-dicarbonyl compounds. Moreover, additional sequences in which the
一种新的二溴化 4,4-二氟-4-bora-3a,4a- diaza - s - indacene (BODIPY) 被报道为一种新的无金属光催化剂。该 BODIPY 显示出与 Ru(bpy) 3 Cl 2相似的光电、电化学和性能特性,Ru(bpy) 3 Cl 2是已知自由基 - 离子转化(例如形成 1,4-二羰基化合物)中最常见的光催化剂之一。此外,使用这种 BODIPY 光催化剂开发了额外的序列,其中生成的氧离子被内部亲核试剂捕获。这些新序列允许直接制备 γ-烷氧基内酯、单保护的 1,4-酮醛和二氢呋喃。这种新的催化剂、方法和伪造的官能团可能是有机合成中的重要工具。
