The choice of solvents is key to the success of this oxyfunctionalization with direct impact on the solubility of substrates, the lifetime of the reactive oxygen species, and the up-scaling of the process. We report an entirely solvent-free continuous-flow photooxygenation that operates at very high substrate/sensitizer ratios and enables high space–time yields.
用单线态氧对烯烃进行光氧化是一种多用途的,原子经济的转变。溶剂的选择是这种氧官能化成功的关键,它直接影响底物的溶解度,活性氧的寿命以及工艺规模的扩大。我们报道了完全无溶剂的连续流光氧合,该光氧合以很高的底物/敏化剂比率运行,并实现了高时空产率。
