generate acyl radicals from readily available aldehydes via hydrogen atom transfer (HAT). Synergistic cooperation, being supported by DFT studies, between earth-abundant iron(III)chloride and 9,10-diphenylanthracene (DPA) to activate the aldehyde for a HAT step proved to be an efficient, economic, and green route for the hydroacylation of electron-deficient alkenes under UV-light irradiation with broad functional
开发了一种双光催化方案,通过氢原子转移 (HAT) 从现成的醛中生成酰基自由基。在 DFT 研究的支持下,地球上丰富的氯化铁 (III) 和 9,10-二苯基蒽 (DPA) 之间的协同合作以激活 HAT 步骤中的醛被证明是一种有效、经济和绿色的加氢酰化途径紫外光照射下的缺电子烯烃,具有广泛的官能团相容性。这种方法可以方便地扩大规模并应用于从可再生原料化学品中生产有价值的材料。
