Rasmussen, et al.anilide (1 g, 6.6 mM) and Pb(0Ac)4 (2 g, 4.5 mM) were stirred together in CH2C1j (50 ml) for 10 min. The reaction mixture was then filtered and steam distilled. The distillate was extracted with CH2C12 to give p-benzoquinone [90 mg, 24% conversion based on Pb(OAc)4 ] characterized by comparison with authentic material, tic, uv, mp 113-114°, and mixture melting point.

Aus Benzo(a)pyren (Ia) werden die Metaboliten (Ib), (Ic), (II), (III) sowie (IVa) und (IVb) erhalten und in ihrer Struktur bestätigt.
