In the cation of the title salt, C9H20NO+·CF3O3S−, the six-membered heterocyclic ring displays a chair conformation. In the crystal, centrosymmetric pairs of cations and anions are linked by N—H...O and O—H...O hydrogen bonds to form rings wit

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 T

The synthesis of two pyridine-stabilised ansa-titanocene oxido complexes is described. Oxidation of the titanocene sources Cpb2Ti(η2-Me3SiC2SiMe3) (Cpb2 = bridged η5-cyclopentadienyl, 1a and 1b) with nitrous oxide yields corresponding oxido compoun

A series of ansa-titanocene triflate complexes are described as model compounds for the elementary steps of light-driven overall water splitting. Titanocene(III) triflate complexes are readily obtained by reaction of a titanocene source with Yb(OTf)3
