说明

一般描述

Tetrabutylammonium acetate is an effective alternative for sodium acetate (NaOAc) due to its good solubility in organic solvents.[1]

应用

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.[1][2] Additionally, TBAAc can also be used as a mild, soluble base in Sonogashira reaction[3] and Heck arylation.[4]

其他说明

用于羟基差向异构化的试剂[5][5]；引导 Heck 型反应的碱性熔融盐[6][7][8]
