WebWordSense Dictionary: périodate - spelling, hyphenation, synonyms, translations, meanings & definitions. Periodate /pəˈraɪ.ədeɪt/ is an anion composed of iodine and oxygen. It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7. Unlike other perhalogenates, such as perchlorate, it can exist in two forms: metaperiodate IO 4 and orthoperiodate IO 6. In this … See more Classically, periodate was most commonly produced in the form of sodium hydrogen periodate (Na3H2IO6). This is commercially available, but can also be produced by the oxidation of iodates with chlorine See more In both the ortho- and metaperiodate the iodine is hypervalent, as it forms more bonds than would classically be allowed. This has been explained in terms of dative bonds, confirming the absence of double bonding in these molecules. Exact structures … See more • Sodium periodate • Potassium periodate • Periodic acid See more Cleavage reactions Periodates can cleave carbon–carbon bonds on a variety of 1,2-difunctionalised alkanes. The most common example of this is diol cleavage, which was also the first to be discovered (Malaprade reaction). In addition to See more
