Method for directly introducing aldehyde group to aromatic ring

The invention relates to a method for directly introducing an aldehyde group to an aromatic ring. A purpose of the invention is mainly to solve the problems of low aromatic hydrocarbon conversion rateand low aromatic aldehyde selectivity in the prior art. According to the technical scheme, the method comprises the step of performing a carbonylation reaction on aromatic hydrocarbon and CO under the catalysis of a catalyst to obtain aromatic aldehyde, wherein the catalyst comprises a carrier, an ionic liquid and a compound-state auxiliary agent metal, the carrier is a silicon-based material, the ionic liquid comprises aluminum halide and an imidazole salt represented by a chemical formula I, R1 and R2 are independently selected from C1-C8 alkyl, X is selected from chlorine and bromine, thealuminum halide is represented as AlY3, Y is selected from chlorine and bromine, and the compound-state auxiliary metal comprises at least one selected from Cu, Fe, Cr, V and Mn.

Synthesis of Substituted Benzaldehydes via a Two-Step, One-Pot Reduction/Cross-Coupling Procedure

The synthesis of functionalized (benz)aldehydes, via a two-step, one-pot procedure, is presented. The method employs a stable aluminum hemiaminal as a tetrahedral intermediate, protecting a latent aldehyde, making it suitable for subsequent cross-coupling with (strong nucleophilic) organometallic reagents, leading to a variety of alkyl and aryl substituted benzaldehydes. This very fast methodology also facilitates the effective synthesis of a 11C radiolabeled aldehyde. Aluminum-ate complexes enable transmetalation of alkyl fragments onto palladium and subsequent cross-coupling.

NOVEL FUSED-RING AROMATIC COMPOUND, PROCESS FOR PRODUCING THE SAME, AND USE THEREOF

A novel fused polycyclic aromatic compound of the present invention is (a) a compound including: a benzodichalcogenophenobenzodichalcogenophene (BXBX) skeleton further having an aromatic ring(s) located outside the BXBX skeleton, or (b) a compound including a BXBX skeleton in which a benzene ring is substituted with a heterocyclic ring. The compound can strengthen intermolecular interaction due to greater π electron orbits. This improves an electron field effect mobility of an organic semiconductor device that is manufactured by use of the compound as an organic semiconductor material. Further, since the number of fused rings included in the compound is small, the compound does not cause problems that generally occur in compounds having an extremely large number of fused rings, i.e., poor solubility in solvent and poor atmospheric stability due to high affinity to oxygen. As a result, the fused polycyclic aromatic compound of the present invention can be preferably used as an organic semiconductor material.

PREPARATION OF NAPHTHALDEHYDES BY CERIUM(IV)AMMONIUM NITRATE OXIDATION OF METHYLNAPHTHALENES.

Naphthalenes with an Me group in the 1-position gave aldehydes in good to excellent yields when oxidized with cerium(IV) ammonium nitrate (CAN) in 50percent HOAc at 85 deg C.Under the same conditions methylnaphthalenes with no Me group in a peri position gave aldehydes in fair yields but also significant amounts of 1,4-naphthoquinone.
