Abstract Binuclear titanocenecomplexes [Cp2Ti(tcm)]2O (4), [Cp2Ti(dca)]2O (5) and [Cp2Ti(dcnm)]2O (6) (tcm− = tricyanomethanide, dca− = dicyanamide and dcnm− = dicyanonitrosomethanide) were synthesized in moderate yields by the reaction of Cp2TiCl2 (1) with respective alkali metal pseudohalide salts in the aqueous solution. When the reaction was carried out in dry organic solvents, mononuclear compounds

The reactions of an acetobromogalactose in mixtures of methanol and one of seven different ionic liquids with varying constituent ions were studied. In general, small amounts of ionic liquid in the reactionmixture led to increases in the rate constant compared to methanol, whilst large amounts of ionic liquid led to decreases in the rate constant; this outcome differs significantly from previous reactions
