Enolization and subsequent methylation of 1,2-di(9-anthryllethanone leads to photolabile E/Z-isomeric a,&substituted dianthrylethylenes. 1,2-Di(9-anthryljpropanone forms a crystalline enol which isomerizes photochemically in solution by a unique H shift. Isolable simple enols typically are stabilize
