Regioselective Palladium-Catalyzed Arylation of 2-Furaldehyde

Organic Letters, 2001
An efficient regioselective method for the direct arylation of 2-furaldehyde to provide a range of pi-diverse 5-aryl-2-formylfuran derivatives is described. The method employs functionalized aryl halides and a catalytic amount of palladium(II) chloride under relatively mild conditions.

2-Furaldehyde (Furfural)

1959
The apparatus used for the preparation of 2-furaldehyde is shown in Fig. 4. The five-liter round-bottomed flask A is connected by means of a cork to the air condenser B, which consists of a tube of diameter 1.8 cm and length 50 cm. A bent side tube C is sealed to B at a distance of 15 cm from its lower end. The bent upper end of the tube B is connected

Syntheses from 4,5-dibromo-2-furaldehyde

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1965
1. The nitration of 4,5-dibromo-2-furaldehyde with nitric acid in acetic anhydride goes with the replacement of the bromine atom in the α-position of the furan nucleus by a nitro group, and 4-bromo-5-nitro-2-furanmethanediol diacetate is formed. 2. In the reaction of butyllithium with 4,5-dibromo-2-furaldehyde acetal the bromide in the α-

Investigation of 5-Hydroxymethyl-2-Furaldehyde and 2-Furaldehyde Compounds in Fruit Juices.

2017
Maillard reactions are responsible for reducing the nutritional value of foods.The formation of the furfural compounds in fruit juices could cause degradationof the nutritional value. Therefore, hydroxymethylfurfuralis the most important quality criteria in the fruit juices.

Acid-Catalyzed 2-Furaldehyde (Furfural) Decomposition Kinetics

Industrial & Engineering Chemistry Research, 2000
Experiments on acid- (HCl-) catalyzed thermal decomposition of 2-furaldehyde in a dilute aqueous solution were performed in a stainless steel batch reactor over a temperature range of 130−170 °C. First-order reaction kinetics best described the experimental results. The rate of reaction increased with temperature and yielded a kinetic activation energy

Metabolic effects of furaldehydes and impacts on biotechnological processes

Applied Microbiology and Biotechnology, 2009
There is a growing awareness that lignocellulose will be a major raw material for production of both fuel and chemicals in the coming decades--most likely through various fermentation routes. Considerable attention has been given to the problem of finding efficient means of separating the major constituents in lignocellulose (i.e., lignin ...

Antibacterial Organophosphorus Compounds: Phosphoranilidohydrazones of 5-Nitro-2-furaldehyde

Journal of Pharmaceutical Sciences, 1993
A series of phosphoranilidohydrazones of 5-nitro-2-furaldehyde was synthesized and evaluated for antibacterial activity. The series was prepared to examine the applicability of phosphoramidic hydrazones as carriers for the antibacterial nitrofuran moiety.
