A hydrophilic inorganic framework based on a sandwich polyoxometalate: Unusual chemoselectivity for aldehydes/ketones with in situ generated hydroxylamine

A hydrophilic inorganic porous catalyst was prepared via the hydrothermal method. The combination of [WZn3(H2O)2(ZnW9O34)2]12- and Co(ii) provides a synergistical catalytic way to promote oximation of aldehyde/ketone with in situ generated hydroxylamine that initially produces an oxime, which further either dehydrates into a nitrile or undergoes a Beckmann rearrangement to form an amide.

Catalytic performance of preyssler anion in selective oximation of aromatic aldehydes

Preyssler catalyst, H14[NaP5W30O110], catalyzes the aldoximation of aromatic aldehydes for the synthesis of Z-isomers in conventional manner and under microwave irradiation. Both pure acid and silica-supported catalysts were used and their activities compared with common catalysts such as K2CO3 and CuSO4. The Preyssler is the catalyst for this reaction.

AlPW12O40 and AlPMo12O40 as highly effective and eco-friendly catalysts for aldoximation of aldehydes under solvent-free conditions

The oxime formation of aromatic aldehydes has directly been carried out with hydroxylamine hydrochloride using heteropoly acids (AlPW12O 40, AlPMo12O40) as catalysts in the absence of solvent. It is found that these heteropoly acids were effective catalysts for the formation of oxime of aldehydes. This method consistently has the advantage of high yields of the products, short reaction time, mild and solvent-free conditions, cleaner reactions and isolation procedures.

P2O5/SiO2 as an efficient reagent for the preparation of Z-aldoximes under solvent-free conditions

A facile and efficient method for the preparation of Z-aldoximes is improved by means of P2O5/SiO2 reagent in solvent-free media. Advantages of this method are the use of inexpensive and selective reagent, with high yields in simple operation, and short reaction time under solvent-free conditions.

Oxidation catalytic system and process for producing ketoisophorone using the same

In the presence of a catalytic system comprising a cyclic base and a complex of a transition metal with an N,N'-disalicylidenediamine, ketoisophorone or a derivative thereof is produced by oxidizing beta -isophorone or a derivative thereof with molecular oxygen with controlling the water content of a reaction system to 1% by weight or less at the initial stage of the reaction. Moreover, the above catalytic system further comprises a basic nitrogen-containing compound. The complex may be an N,N'-disalicylidene C2-5 alkylenediamine complex with manganese, iron, cobalt, copper, or vanadium. The cyclic base may be an alicyclic or aromtaic compound having at least two nitrogen atoms. As the basic nitrogen-containing compound, a Schiff base such as an imino compound and an anil compound can be used. The proportion of the nitrogen-containing compound to the complex is about 0.1/1 to 20/1 (molar ratio). With the above oxydation catalytic system, there can be obtained ketoisophorone and derivatives thereof with high efficiency.

Hydroformylation of olefins using azoxy-dentated ligands

At a temperature in the range 100° C to 225° C the destructive dissociation of cobalt carbonyl compounds to cobalt metal and residue is inhibited by the action of one or more azoxy-dentated chelation ligands.
