Abstract
Irradiation of triphenyl-(la), tri-p-tolyl-(lb), or tri-p-anisylvinyl bromide (lo) in methanol gave the vinyl ethers 4 and the phenanthrenes 5. A study of [2-13C]-labeled bromides showed that@-aryl rearrangement takes place in the photochemically generated vinyl cations 3*. Irradiation of triaryl [2-13C] vinyl bromides I* in trifluoroethanol and analpie of the extent of scrambling from C-2 to C-1 in the trifluoroethyl vinyl ethers 8 showed 38%, 72%, and 92% ...
