چکیده
The title compound (HMF), C(6)H(6)O(3), is one of the products of acid-catalyzed dehydration of high-fructose corn syrup, and has been shown to be toxic to honey bees. The compound was crystallized at 276 K, and it was found that the two independent mol-ecules in the asymmetric unit form an infinite O-H⋯O hydrogen-bonding chain that is linked into a three-dimensional network structure by weak inter-molecular C-H⋯O contacts.

متن کامل5-(Hydroxymethyl)furan-2-carboxylic acid
In the title compound, C(6)H(6)O(4), the furan ring is nearly coplanar with the carboxyl group, the maximum atomic deviation being 0.0248 (9) Å. The crystal packing is stabilized by classical O-H⋯O and weak C-H⋯O hydrogen bonding.
متن کامل5-[(9H-Fluoren-9-ylidene)methyl]furan-2-carbonitrile
The title compound, C(19)H(11)NO, is stabilized by one intra-molecular C-H⋯O hydrogen bond. The compound can be synthesized in good yield (49%), by transformation of functional groups [starting with 5-(fluoren-9-ylidenemeth-yl)furan-2-carbaldehyde]. The flourene and furan ring systems are nearly coplanar, with a dihedral angle of 6.36 (7)°.
متن کاملTheoretical Study of the Conversion from 5-hydroxymethylfuran-2-carbaldehyde to 2-hydroxy-5-methylene-2,5-dihydro-furan-2- Carbaldehyde in the Levulinic Acid Formation Process
A novel reaction route was proposed from 5-hydroxymethylfuran-2carbaldehyde (HMFCA) to 2-hydroxy-5-methylene-2,5-dihydro-furan-2carbaldehyde (HMDFC) on the basis of the mechanism previously offered by Horvat, to account for the formation mechanism of levulinic acid. The probabilities of the two mechanisms were compared by Gaussian 03 software. It was found that the conversion from HMFCA to HMDF...
