Spectroscopic identification of the nickel acylate complex
Simunic, Joan L.,Pinhas, Allan R.
, p. 1358 - 1360 (1987)
NMR and IR spectral data of the pentanoyl nickelate complex are presented and are consistent with a mononuclear nickel complex. This nickel acylate complex is thermally stable in THF at ambient temperature (+20°C) for prolonged periods (24 h) but decomposes rapidly in air.

Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C-H and C-C bonds was accessible to the one-pot substitution reaction.

An effective process for the conversion of carboxylic acid to ketone has been discovered. In this process, carboxylic acid has been activated using p-toluene sulphonyl group. Under the optimized condition, aromatic, aliphatic heteroaromatic carboxylic acids have been proved to be good substrates for this methodology. The byproduct of this reaction can be removed very easily during work up process. Also, one equivalent of organometallic reagent is sufficient to complete this transformation.
