Allgemeine Beschreibung
Cesium pivalate is an organic base widely used in palladium-catalyzed cross-coupling and carbonylation reactions due to its solubility in organic solvents.
Anwendung
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.

The synthesis of various substituted fluoren-9-ones has been accomplished by a novel palladium-catalyzed cyclocarbonylation of o-halobiaryls. The cyclocarbonylation of 4'-substituted-2-iodobiphenyls produces very high yields of 2-substituted fluoren-9-ones bearing either electron-donating or electron-withdrawing substituents. 3'-Substituted 2-iodobiphenyls afford in excellent yields with

The 1,4-palladium shift strategy allows the functionalization of remote C-H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3 )-H activation, 1,4-palladium shift, and amino- or alkoxycarbonylation, which generates a variety of amides

Pd-catalyzed arylation or benzylation of nitroazoles using aryl sulfonates or benzyl acetates is described. Electronically varied aryl tosylates and mesylates, as well as benzyl acetates, afford the arylated and benzylated products. Arylation of nitrobenzene is also reported. The relative rate
