In conclusion, imine radicals 5 and 15 can be generated from the manganese(III), silver(II) oxidation of 2-amino-1,4-benzoquinones. These free radical reactions provide efficient methods for the generation of the dimeric products 4 and 14. In the presence of styrene, twistane 17 was afforded from 2-phenylamino-1,4-benzoquinone 1 via a radical annulation reaction of imine radical 5.
