Silver perchlorates

Perhalates. Whereas silver perchlorate [7783-93-9] AgClO, and silver periodate [15606-77-6] AglO, are well known, silver perbromate [54494-97-2] AgBrO, has more recendy been described (18). Silver perchlorate is prepared from silver oxide and perchloric acid, or by treating silver sulfate with barium perchlorate. Silver perchlorate is one of the few silver salts that is appreciably soluble in organic solvents such as glycerol, toluene, and chlorobenzene.

Apart from the rearrangement of the tricyclo[4.1.0.03/7]heptane to the bicyclo[2.2.1]hept-2-ene system under acid catalysis, it can be effected by silver(I) perchlorate [silver(I) assisted ionization]19 and by photolysis at 185 nm.20... 

Paulsen and Schnell [225] have also converted the lactosamine derivative (315) into the derivative (320) and condensed this with the azidoglucosyl bromide (329) in the presence of silver perchlorate — silver carbonate to give an a-linked trisaccharide which was deprotected to give the trisaccharide AAcglc-a-( 1 ->4)-gal-P-(l ->4)-AfAcglc which has been shown to be present in blood-group substances. 

Caution must be exercised when handling perchlorates. Silver perchlorate is explosive grinding it in a mortar should be avoided. For use in reference electrodes, it may be prepared by anodic dissolution of silver in a perchlorate medium [202]. Evaporation of solutions of organic perchlorates is discouraged but, if necessary, must occur in vacuo and at moderate temperatures. Even sodium perchlorate, which can be dried at 100°C without undue risk, may cause explosions when heated with an organic solvent. 

Nakajima and coworkers also prepared 1,2-cis-glycosides, including kanosamine, kanamycin A,109 and paromamine derivatives,110 by the reaction of appropriately protected a-D-glycopyranosyl halides of aminodeoxy-D-glucoses with deoxystreptamine derivatives in the presence of silver perchlorate, silver carbonate, and Drierite in benzene or chloroform containing 10-20% of 1,4-dioxane.

Flow or agitation of substance may generate electrostatic charges due to low conductivity.
