General description
Cesium pivalate is an organic base widely used in palladium-catalyzed cross-coupling and carbonylation reactions due to its solubility in organic solvents.
Application
Cesium pivalate can be used as a base to synthesize:
- Fluoren-9-one derivatives by cyclocarbonylation of o-halobiaryls in the presence of palladium catalyst.
- Fused heterocycles (dihydrobenzofurans and indolines) from o-bromo phenol and aniline precursors via Pd-catalyzed intramolecular coupling of two C(sp3)-H bonds.
- Amides and esters derivatives containing a quaternary β-carbon atom by Pd-catalyzed C-H activation and amino/alkoxycarbonylation reaction.
