The conversion of ketones to esters has been achieved through the use of Cu catalyst and tetrabutylammonium nitrite. This reaction involves the activation of the less activated C-C bond, and the alkyl group is removed as a leaving group. Various isopropyl ketones are found to be good substrates for this reaction.

A general protocol for the palladium-catalyzed carbonylation of aryl tosylates and mesylates to form esters has been developed using a catalyst system derived from Pd(OAc)2 and the bulky, bidentate dcpp ligand. The system operates under mild conditions: atmospheric CO pressure and temperatures of 80-110 °C. A broad substrate scope has been demonstrated allowing carbonylation of electron-rich, electron-poor, and heterocyclic tosylates and mesylates, and the reaction shows wide functional group tolerance.

Bimolecular Reactions of Mutagenic N-Acetoxy-N-alkoxybenzamides and N-Methylaniline
Campbell, John J.,Glover, Stephen A.

N-Methylaniline reacts bimolecularly with mutagenic N-acetoxy-N-alkoxybenzamides and the resultant N-alkoxy-N-(N-methylanilino)benzamides undergo a novel, concerted rearrangement to alkylbenzoates and 1-methyl-1-phenyldiazene which dimerizes to 1,4-dimethyl-1,4-diphenyl-tetrazene.
The Influence of Water Traces on Some Liquid/Solid Phase Transfer Catalysis Processes (Applications of Phase Transfer Catalysis, Part 42)
Dehmlow, Eckehard V.,Raths, Hans-Christian
, p. 2901 - 2917 (2007/10/02)
Rates of solid/liquid phase transfer catalytic conversions (an ester formation, an ether formation, a cyanide displacement, and a dichlorocarbene generation) were investigated using onium salts and dicyclohexano-18-crown-6 as catalysts and varying the (very low) water content of the system.The influence of the water traces varies strongly with the types of anions and catalysts.
