Phosphorus- or sulfur-centered radicals generated from the reaction of manganese (III) acetate with dialkyl phosphonates or arylthiols undergo selective additions to conjugated alkynes followed by cyclization and rearomatization to afford 2-phosphonyl- or 2-thioaryl-substituted indenones in fair to good yields.
由乙酸锰 (III) 与膦酸二烷基酯或芳硫醇反应生成的磷或硫中心自由基,选择性加成到共轭炔烃上,然后环化和重构化,得到 2-膦酰基或 2-硫芳基取代的茚酮。产量。
