A highly efficient sulfonylation of para-quinone methides with sulfonyl hydrazines in water has been developed on the basis of the mode involving a tetrabutyl ammonium bromide (TBAB)-promoted sulfa-1,6-conjugated addition pathway. This reaction provides a green and sustainable method to synthesize various unsymmetrical diarylmethyl sulfones, showing good functional group tolerance, scalability, and regioselectivity. Further transformation of the resulting diarylmethyl sulfones provides an efficient route to some functionalized molecules.

To explore environmentally benign method for preparing TiO2, composite photocatalysts TiO2 immobilized on activated carbon fibers (TiO2/ACF) were prepared in caprolactam tetrabutyl ammonium bromide ionic liquid (CPL-TBAB ILs). The TiO2/ACF composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The effects of different preparation condition were discussed by degradation of methyl orange (MO). The results showed that nanoTiO2 particles of mixed grain phase were well deposited on the activated carbon fiber surface. 96% of MO was removed under optimal preparation conditions.

A new series of benzamido alkyl naphthols were synthesized from the multi-component reaction of 4-(3′-methylthioureido)benzamide, aromatic aldehydes and 2-naphthol. Molten tetrabutyl ammonium bromide was used as a very efficient medium for this reaction while the use of common organic solvents gave no or poor yields. This method is an interesting instance of using molten salt as a medium in multicomponent reactions.
