Abstract

Abstract : Visible light irradiation of an ansa -titanocene(iv ) dihydroxido complex Me4 Si2 (C5 Me4 )2 Ti(OH)2 induces highly selective Ti–O bond activation to exclusively yield Ti(iii ) complexes. Abstract : Irradiation of a substituted ansa -titanocene(iv ) dihydroxido complex with visible light induces Ti–O bond dissociation. In contrast to previous studies on structurally similar unbridged complexes, no side reactions are observed and formation of the Ti(iii ) species is highly selective. The formation of OH radicals was proved using a biradicaloid species.
