Radical hydroxymethylation using formaldehyde as a C1 synthon is challenging due to the reversible and endothermic nature of the addition process. Here we report a strategy that couples alkyl iodide building blocks with formaldehyde through the use of photocatalysis and a phosphine additive. Halogen-atom transfer (XAT) from α-aminoalkyl radicals is leveraged to convert the iodide into the corresponding
由于加成过程的可逆和吸热性质,使用甲醛作为 C1 合成子的自由基羟甲基化具有挑战性。在这里,我们报告了一种通过使用光催化和膦添加剂将烷基碘构建块与甲醛结合的策略。利用来自 α-氨基烷基自由基的卤素原子转移 (XAT) 将碘化物转化为相应的开壳物质,而通过用 PPh 3捕获瞬态 O 自由基,使其随后加入甲醛变得不可逆。该事件提供了一个磷酰基自由基,它重新生成了烷基自由基并提供了羟甲基化的产物。
