Radical anions (or the corresponding salts) derived from ketones by addition of an electron R2C·–O− R2C−–O·.
Note: Ketyls produce two types of conjugate acids: R2C.–OH and R2CH–O.. The former are α-hydroxyalkyl radicals and the latter are alkoxyl radicals, but they have also been called ketyls in photochemistry.
