Beschreibung

Allgemeine Beschreibung

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

Anwendung

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.
