photosensitizer: We introduce a method for selective photoinduced alkylations of electron‐rich heterocompounds with electron‐deficient allyl bromides in the presence of 2,6‐lutidine at 365 or 405 nm. Mechanistic investigations reveal that a colored intermediate formed from 2,6‐lutidine and alkyl bromide is involved in the photoactivation. Our approach uses commercially available reagents and a straightforward
无需复杂的光敏剂:我们介绍了一种在365或405 nm处有2,6-核苷存在的情况下,用缺电子的烯丙基溴对富电子的杂化合物进行选择性光诱导烷基化的方法。机理研究表明,由2,6-二甲基吡啶和烷基溴形成的有色中间体参与了光活化。我们的方法使用市售试剂和简单明了的方案。
