Palladium ethyl 2- benzoat

Methyl />-acetylbenzoate has been prepared by the esterification of -acetylbenzoic acid with methanol in the presence of hydrogen chloride,6 by the hydrogenation of methyl -trichloro-acetylbenzoate in the presence of a palladium on calcium carbonate catalyst,6 and by the air oxidation of methyl / -ethyl-benzoate.4... 

The transformation of diazoester 244 (R1 = Me, R = /-Pr) to substituted ethyl benzoate 567a, catalyzed with palladium(II), proceeded as a spontaneous desulfurization of unstable thiepin derivative 566a.285 The isolation of the similar intermediate 566b will be mentioned in Section G,3. 

The low melting and liquid halide salts in Table 1 have found utility as ILs. McNulty et al. have reported high yields for palladium cross-coupling reactions using entry 9 (CYPHOS ILlOl) as a recyclable solvent/catalyst system [15], Similarly, Kaufmann et al. have reported that entry 12 can be used repeatedly with the same palladium catalyst to obtain high conversions of Heck coupling products [16]. Ramani has demonstrated that entry 9 can be successfully employed for a variety of reactions such as quantitative Michael addition of amines to acrylate esters [17], palladium-catalyzed carbonylation of iodobenzene to obtain ethyl benzoate [9], and Heck coupling of iodobenzene and ethyl acrylate [19]. 

Cyanocarboxylic acid esters. 2-Oximinocyclohexanone dimethyl ketal, trimethyl orthoformate, and a little methanesulfonic acid added at -70° under Ng to liq. SO2, and refluxed 0.5 hr. at ca. -10° methyl 5-cyanopentanoate. Y 97%. -Similarly at 72° Benzil monoxime and triethyl orthoformate -> benzonitrile (Y 95%) and ethyl benzoate (Y 98%). M. M.

Scheme 9.164. A representation of the conversion of an aryl halide (iodobenzene) into the ester of a carboxylic acid (ethyl benzenecarboxylate [ethyl benzoate]) by reaction with carbon monoxide (CO) in the presence of alcohol (ethanol, ethyl alcohol, CH3CH2OH), triethylamine [(CH3CH2)3Nj, and palladium(II) chloride (PdCl2).
