Conversion of donor-substituted homonaphthoquinones to indenonaphthoquinones via intramolecular photoinduced electron-transfer
Abstract
Irradiation of bis(p-anisyl)-or p-anisylphenyl-homonaphthoquinones 1a,b in the presence of Mg(ClO4)2 results in the formation of indenonaphthoquinones 2a,b via intramolecular photoinduced electron-transfer.
