Catalytic ketonisation over oxide catalysts. Part IX. Single step synthesis of aliphatic saturated and unsaturated C11 - C 13 ketones from carboxylic acids
Glinski,Gibka
, p. 299 - 302 (2007/10/03)
Metameric undecan-x-ones (x = 2-6), dodecan-y-ones (y = 2-5), tridecan-z-ones (z = 4-7) and two unsaturated aliphatic ketones were prepared by vapor phase ketonisation of the appropriate monocarboxylic acids in the presence of 20 wt% MnO2/Al2O3 catalyst under flow conditions. The ketones were obtained in yields between 48 and 89% in a multigram scale (80-250 g). Their physical and spectral data have been determined.
New version of the TEMPO-based catalytic system for the oxidation of alcohols to aldehydes
Kowalczyk,Skarzewski
, p. 1413 - 1417 (2007/10/03)
A new chemoselective catalytic system for the title oxidation was developed using methyltrioxorhenium (3 mol%), KBr (10 mol%) and TEMPO (3 mol%) as co-catalysts and Oxone as a terminal oxidant.
One-pot dialkylation of allylphenylsulfide induced by aminoalkoxides- activated NaNH2. Application to the synthesis of unsymmetrical ketones

It is shown that the activation of NaNH2 by sodium aminoalkoxides, leading to new superbases, induced an efficient one-pot dialkylation of allylphenylsulfide. The regioselectivity of the reaction (α,α' vs α,γ) was found as strongly dependent on the nature of the alkyl halide. As an application, α,γ dialkylated products were efficiently converted Into the corresponding unsymmetrical ketones.
