Description

General description

Pivalic acid is a carboxylic acid, employed as a ligand to synthesize cerium(IV) hexanuclear clusters.

Application

Pivalic acid can be employed:

As a co-catalyst with palladium for the arylation of unactivated arenes and N-heterocycles.
As an additive to facilitate the carbonylative suzuki reactions to synthesize biaryl ketones from aryl iodides and arylboronic acids by using palladium nanoparticles as catalyst.
In the cyclization reaction of benzamides with alkynes to synthesize isoquinolones in the presence of 8-aminoquinoline ligand and cobalt catalyst.
