A visible-light-induced metal-free synthesis of 1,4-dicarbonyl compounds from alkyne-containing aryl iodides via photochemical C-I bond cleavage, intramolecular cyclization, oxidation, and intermolecular radical coupling sequence is reported. TEMPO was employed as the oxygen atom donor in this transformation. This protocol provided a new strategy for the synthesis of 1,4-dicarbonyl bifluorene compounds.
报道了一种可见光诱导的无金属合成方法，该方法通过光化学C-I键裂解、分子内环化、氧化和分子间自由基偶联序列，从含炔基的芳基碘化物合成1,4-二羰基化合物。在该转化过程中，TEMPO被用作氧原子供体。该方法为1,4-二羰基联芴化合物的合成提供了一种新策略。
