A method for the conversion of primary, secondary and tertiary alcohols into the corresponding THF ethers at room temperature and primary and secondary alcohols into the corresponding THP ethers, has been developed using titanium(III) species generated from a catalytic amount of titanocene dichloride or (4R,5R)-(-)-2,2-dimethyl-alpha,alpha,alpha?,alpha?-tetra(1-naphthyl)-1,3-dioxolane-4,5-dimethanolatotitanium(IV) dichloride:acetonitrile adduct together with manganese(0) as a reductant and bromoform in THF or THP as the solvent. A radical mechanism is proposed for this transformation revealing an intriguing role of the solvent in the single-electron transfer reactions catalysed by the low valent TiIII system. A set of primary, secondary and benzylic alcohols have been converted into the corresponding THF and THP ethers and tertiary alcohols into the corresponding THF ethers using a catalytic amount of titanium dichloride in good yields and mild reaction conditions.

The tripledecker sandwich complex BF4 (I) reacts with (C5H5)2Ti(SR)2 (R=Me, Ph) and (C5H5)2Mo(SR)2 (R=Me, Ph, But) to produce the dinuclear heterometallic compounds <(C5H5)2M(mu-SR)2Ni(C5H5)>BF4 (V, VI, XI-XIII).The temperature dependence of the 1H NMR spectra of the Ti-Ni complexes V, VI is best explained by an inversion at the sulfur atoms of the bridging SR units which, above +35 deg C, occurs rapidly.The chemical shifts of the 1H and 13C NMR signals of the cyclopentadienyl ligand coordinated to nickel in the compounds <(C5H5)2Mo(mu-SBut)2Ni(C5H4R)>BF4 (XIII: R=H, XIV: R=Me) are also strongly temperature-dependent presumably due to an equilibrium between a diamagnetic low-spin and a paramagnetic high-spin isomer.Molecular orbital calculations indicate that the spin crossover is probably a consequence of a flattening at the sulfur atoms caused by the t-butyl substituents.The X-ray structural analysis of XIII shows the presence of a folded four-membered MoS2Ni ring having the t-butyl groups on the inside.In accordance with the MO calculatins, the sulfur atoms are less pyramidal than in analogous complexes.The NMR spectrum of the compound BF4 (XXIII) which is prepared from C5H5(PMe3)Co(SPh)2 and I, does not vary with the temperature.

A radical merry-go-round. An electron is transferred from a titanocene(III) complex to the substrate and finally back to the catalyst in a novel atom-economical tandem reaction. Complex structures can be readily accessed (see scheme). The unprecedented mechanism involving a homolytic cleavage of a Ti-O bond is supported by DFT calculations.

The crystal structure of 4 is known and the complex is isomorphous with 5. 1-5 form mutually similar macrocyclic tetranuclear complexes in which the alternating Fe(C5H4Se)2 and M(C5H4R)2 centers are linked by selenium bridges. The thermogravimetric analysis (TGA) of 1-3 under a helium atmosphere indicated that the complexes undergo a two-step decomposition upon heating. The final products were identified using powder X-ray diffraction as FexMSe2, indicating their potential as single-source precursors for functional materials.
