in N-heterocyclic carbene (NHC) organocatalysis, undergo Norrish type II elimination reactions under irradiation with UVA light in analogy to structurally related aromatic ketones. Moreover, efficient Norrish-Yang cyclization was observed from an adamantyl-substituted derivative. These results further demonstrate the ability of NHCs to influence the absorption properties and photochemical reactivity
已经研究了衍生自脂肪族羧酸的酰基唑盐的光化学反应性。这些物种作为 N-杂环卡宾 (NHC) 有机催化中生成的中间体的模型,在 UVA 光照射下进行 Norrish II 型消除反应,类似于结构相关的芳香酮。此外,从金刚烷基取代的衍生物中观察到有效的 Norrish-Yang 环化。这些结果进一步证明了 NHCs 在催化循环过程中影响羰基的吸收特性和光化学反应性的能力。
