摘要

在丙酮中对苯甲酸苯乙酯与苯酚或苯甲醚进行光解，可形成 1,4-二羰基化合物，即苯乙酯分子与丙酮的偶联产物。反应是通过电子和/或质子从三重赋形剂中转移而发生的，从而形成苯羰基自由基，然后与丙酮的烯醇形式相加。该反应也会以分子间方式与外部电子供体发生。

Photochemical coupling reaction of phenacyl benzoate with acetone to form 1,4-dicarbonyl compound enabled by charge transfer

Photolysis of phenacyl benzoates tethered with a phenol or anisole in acetone resulted in the formation of 1,4-dicarbonyl compounds, coupling products of the phenacyl moiety with acetone. The reaction occurs via electron and/or proton transfer from a triplet exciplex, leading to the formation of a phenacyl radical, which then adds to the enol form of acetone. The reaction also occurs in intermolecular fashion with external electron donors.
