Gleu, Karl published the artcileAction of iodine monochloride upon heterocyclic bases, Name: Pyridine Iodochloride complex, the publication is Journal fuer Praktische Chemie (Leipzig) (1936), 257-64, database is CAplus.
M ICl solution is prepared from 110.7 g. KI and 71.3 g. KIO3 in 833 cc. 6 N HCl, made up to a l. with H2O. C5H5N in 6 N HCl, treated with hot ICl solution, gives C5H5N.HICl2, yellow, m. 182°; washing with H2O and crystallization from C6H6 gives C5H5N.ICl, pale yellow, m. 135°. Quinoline.HICl2, yellow, m. 118°; the ICl derivative m. 157°. Isoquinoline.HICl2, yellow, m. 155°; the ICl compound m. 158°. Acridine.HICl2, yellow, m. 220°; it is stable toward H2O. o-Phenanthroline.HICl2, m. 167°, stable to H2O; the p-isomer, C12H8N2.(HICl2).2H2O, orange-red, m. 197°. 8-Hydroxyquinoline and 2 mols. ICl give the 5,7-di-I derivative, pale yellow, m. 210°; 1 mol. ICl gives the 5-1 derivative, m. 135°; 8-aminoquinoline and 2 mols. ICl give the 5,7-di-I derivative, pale yellow, m. 151°; 5-I derivative, yellow, m. 125°. 6,8-Diiodo-5-hydroxyquinoline, m. 134° (decomposition); 8-I derivative, m. 153°. 5-Aminoquinoline iodochloride, m. 198°; 6-hydroxyquinoline iodochloride, m. 252°. 6-Aminoquinoline.HICl2, orange-red, m. 206°.
