METHOD FOR PREPARING HYDROXY OXIME

The present invention relates to a process for the preparation of hydroxy oximes. More particularly, the present invention relates to a method for preparing a hydroxy oxime capable of improving the yield of each process step and reducing the generation of ketoxime by-products which reduce the metal extractability of the hydroxy oxime as an extractant.

N-Heterocyclic Carbene/Carboxylic Acid Co-Catalysis Enables Oxidative Esterification of Demanding Aldehydes/Enals, at Low Catalyst Loading

We report the discovery that simple carboxylic acids, such as benzoic acid, boost the activity of N-heterocyclic carbene (NHC) catalysts in the oxidative esterification of aldehydes. A simple and efficient protocol for the transformation of a wide range of sterically hindered α- and β-substituted aliphatic aldehydes/enals, catalyzed by a novel and readily accessible N-Mes-/N-2,4,6-trichlorophenyl 1,2,4-triazolium salt, and benzoic acid as co-catalyst, was developed. A whole series of α/β-substituted aliphatic aldehydes/enals hitherto not amenable to NHC-catalyzed esterification could be reacted at typical catalyst loadings of 0.02–1.0 mol %. For benzaldehyde, even 0.005 mol % of NHC catalyst proved sufficient: the lowest value ever achieved in NHC catalysis. Preliminary studies point to carboxylic acid-induced acceleration of acyl transfer from azolium enolate intermediates as the mechanistic basis of the observed effect.

ESTER SYNTHESIS USING HETEROGENEOUS AU/TIO2 CATALYST

A process for direct esterification of an alkyl aldehyde with an alkyl alcohol to produce an alkyl ester is disclosed. The process comprises reacting an alkyl aldehyde with an alkyl alcohol in the presence of an Au/TiOa catalyst, a base and an enal or oxygen to form an ester and an aldehyde. The process avoids liberation of water and avoids the step of oxidation of the alkyl aldehyde to an alkyl acid.
