Muathen, Hussni A. published the artcileMild and efficient iodination of aromatic compounds with pyridine-iodine monochloride complex (PylCl), Application In Synthesis of 6443-90-9, the publication is Journal of Chemical Research, Synopses (1994), 405, database is CAplus.
A wide range of aromatic compounds (e.g., C6H6) have been effectively iodinated with a pyridine-iodine monochloride complex (I). Condensed polycyclic iodides, which are not readily obtained via direct iodination, can be prepared indirectly via their corresponding organomercurials in 1 step. Some benzoid and nonbenzoid heterocycles (e.g., indole) are iodinated with I.
Journal of Chemical Research, Synopses published new progress about 6443-90-9. 6443-90-9 belongs to iodides-buliding-blocks, auxiliary class Pyridines, name is Pyridine Iodochloride complex, and the molecular formula is C5H5ClIN, Application In Synthesis of 6443-90-9.
