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.
