Description General description Tetrabutylammonium acetate (TBAA) is a phase transfer catalyst (PTC). Application Tetrabutylammonium acetate can be used: • To catalyze the alkynylation of carbonyl compounds with trimethylsilylacetylenes providing good yields of propargylic alcohols. • Along with tetrabutylammonium bromide (TBAB) as a molten reaction medium in the synthesis of 4-aryl-2-quinolones. • As a promoter in the regioselective direct arylation of azoles (1-methylpyrazole, oxazole, and thiazole) with aryl bromides in presence of palladium acetate catalyst. • As an ionic liquid to dissolve cellulose in the presence of DMSO co-solvent. • As an activator in the synthesis of disubstituted alkynes through copper-free Sonogashira coupling reaction.
