发明名称 Process for preparation of aromatic halides from aromatic amines
摘要 The present invention provides a process for producing aromatic bromide or aromatic iodide from an aromatic amine derivative using nitrite ion and holodimethylsulfonium halide generated in situ from hydrobromic acid/DMSO or hydriodic acid/DMSO. The process for producing compounds of the formula (1) is disclosed (1) wherein X is bromine or iodine: Y is carbon C or nitrogen; R<1>, R?2?, R<3>, R<4 >which may be the same or different and are selected independently from the group consisting of a hydrogen, a hologen, a C1-C8 alkyl, a C1-C10 alkoxy, a nitro, a formyl, an aryl, a benzyl, a C2-C10 alkylcarbonyl and an arylcarbonyl, provided that adjacent groups as selected from among R<1>, R<2>, R<3>, R<4 >and R<1 >may combine to form a ring.
