An air-stable uninuclear complex of bis(isopropylcyclopentadienyl) zirconium perfluorooctane sulfonate (1a·H2O·3THF) was successfully synthesized by the reaction of (i-PrCp)2ZrCl2 with C17SO3Ag. The c

Fe2(SO4)3·xH2O on silica has been found to be a novel efficient catalyst for the direct nucleophilic substitution of alcohols in solvent-free conditions. In this reaction system, the alcohols can react with various nucleophilic reagents for the convenient construction of C-C bonds and C-N bonds with the benefits of high conversion, no requirement to use excessive amounts of the nucleophile, only a catalytic amount of iron catalyst required, solvent-free and benign reaction conditions, and the feasible reusability of the catalyst.

A zinc-based ionic liquid ([CHCl][ZnCl2]2) was found to be an excellent reaction medium for the direct nucleophilic substitution reactions of alcohols. The high conversion, high selectivity, easy separation procedure, catalyst reusability and no necessity of excessive nucleophiles make the chemical process cleaner. This reaction was believed to work through the carbocation mechanism and the existence of carbocation was detected by UV-vis spectroscopy. It was suggested that the hydroxyl group on the choline cation was the major inducement for the formation of special microstructures which could provide adequate stability for the carbocation in the reaction systems and increase the reactivity and selectivity.
