Application
Tetrabutylammonium acetate (TBAAc) is a good source of nucleophilic acetate ion for SN2 substitution reactions. It is commonly used to displace sulfonates and allylic halides to get corresponding acetates. Additionally, TBAAc can also be used as a mild, soluble base in Sonogashira reaction and Heck arylation.
General description
Tetrabutylammonium acetate is an effective alternative for sodium acetate (NaOAc) due to its good solubility in organic solvents.
