The Uses of Tetrabutylammonium acetate
Tetrabutylammonium Acetate acts as a catalyst in organic syntheses of anion sensors.
What are the applications of Application
Tetrabutylammonium acetate is a catalyst for the alkynylation of carbonyl compounds with trimethylsilylacetylenes
What are the applications of 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.
General Description
Tetrabutylammonium acetate (TBAA) is a phase transfer catalyst (PTC).
Advantages
Tetrabutylammonium Acetate (TBAAc) could be used as the Buffer Layer between the SnO2 Electron Transport Film and CsPbI3 within All-Inorganic Perovskite Solar Cells. The TBAAc buffer layer suppresses heterogeneous CsPbI3 perovskite nucleation, which leads to larger grain sizes, better charge transfer, and the enhancement of the photovoltaic performance of CsPbI3 PSCs. In addition, interfacial trap-assisted recombination was reduced and the charge extraction efficiency was remarkably improved[1].
