Industrialized synthetic method for halogen benzoic acid derivative

The invention discloses an industrialized synthetic method for a halogen benzoic acid derivative. The formula (I) of the halogen benzoic acid derivative is shown in the description, wherein a plurality of Rs are alkyls of C1-C20, and a plurality of Xs are halogens; the industrialized synthetic method comprises the following steps that alkyl substituted benzoic acid and water are added into a reaction container, halogen simple substances are added, a heating reaction is performed, the reaction is complete, and post processing is performed to obtain the target product halogen benzoic acid derivative. According to the industrialized synthetic method for the halogen benzoic acid derivative, no solvent needs to be recycled, little consumption is consumed, little waste gas, water and industrialresidues are caused, and by-product haloid acid can be directly sold or used for producing other products; accordingly, the industrialized synthetic method for the halogen benzoic acid derivative is safe, environmentally friendly and low in cost, and therefore the wide industrial application prospect is achieved.

Bromodecarbonylation and bromodecarboxylation of electron-rich benzaldehydes and benzoic acids with oxone and sodium bromide

Benzaldehydes and benzoic acids bearing ortho- and paraelectron donating substituents having unshared electron-pair have undergone bromodecarbonylation or bromodecarboxylation on treatment with sodium bromide in the presence of Oxone in aqueous methanol.

CATALYTIC AND STOICHIOMETRIC BROMINATION OF AROMATIC COMPOUNDS IN AQUEOUS TRIFLUOROACETIC ACID IN THE PRESENCE OF NITROGEN-CONTAINING OXIDIZING AGENTS

The mono- and polybromination of benzene, halogenobenzenes, toluene, p-xylene, anisole, biphenyl, benzotrifluoride, benzoic acid, p-nitro- and p-carboxytoluene, p-methoxybenzonitrile, tetralin, and naphtalene were studied in trifluoroacetic acid and its aqueous solutions in systems containing stoichiometric amounts of bromine or alkali-metal bromide and stoichiometric or catalytic (in the presence of oxygen or air) amounts of nitrogen-containing oxidizing agent (nitrogen(IV) oxide, alkali-metal nitrate or nitrite).It is suggested that the brominating agent under the investigated conditions is nitryl bromide NO2Br.Under the conditions of catalytic bromination anthracene is oxidized to anthraquinone with a preparative yield.
