Descrição

Descrição geral

Tetrabutylammonium acetate (TBAA) is a phase transfer catalyst (PTC).

Aplicação

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.
