groups with palladium(II) acetate in a mixed solvent of benzene and acetic acid gave cyclodimerized products, i.e. 5,6,11,12-tetrahydrodibenzo[b,f][1,5]diazocine derivatives in good yields, via novel C–C bond formation, along with small amount of acetoxylated or demethylated products. Radical cation species was suggested as a cyclodimerization intermediate.
由给电子基团对位取代的N,N-二甲基苯胺与乙酸钯(II)在苯和乙酸的混合溶剂中反应得到环二聚产物,即5,6,11,12-四氢二苯并[b,f] [1,5] 重氮辛衍生物通过新的 C-C 键形成,以及少量乙酰氧基化或去甲基化产物,收率良好。自由基阳离子物种被建议作为环二聚中间体。
