Description

Application

Tetrabutylammonium hexafluorophosphate (TBAPF₆) can be used:

• As a catalyst in the synthesis of 3,4-dihydropyrimidin-2(1H)-one and 3,4-dihydropyrimidine-2(1H)-thione derivatives via Biginelli reaction.
• Along with 1-ethyl-3-methyl imidazolium hexafluorophosphate as a supporting electrolyte in non-aqueous redox flow batteries.
• As a supporting electrolyte in the electropolymerisation.

Tetrabutylammonium hexafluorophosphate can be used as a supporting electrolyte for the formation of cyclic disulfide moiety of 3,5-diimido-1,2-dithiolane derivatives by S-S coupling of dithioanilides.
