Classically, periodate was produced in the form of sodium hydrogen periodate (Na 3 H 2 IO 6). [3] This commercially available, but can also be produced by the oxidation of iodates with chlorine and sodium hydroxide. [3] [4] Or, similarly, from iodides by oxidation with bromine and sodium hydroxide: NaIO 3 + Cl 2 + 4 NaOH → Na 3 H 2 IO 6 ...

Periodic acid (/ ˌ p ɜːr aɪ ˈ ɒ d ɪ k / per-eye-OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H 5 IO 6, and metaperiodic acid, which has the formula HIO 4.
The development of the Lemieux–Johnson oxidation was preceded by an analogous process, developed by Lemieux and Ernst Von Rudloff (sometimes called the Lemieux-Von Rudloff reaction), which used an aqueous solution of sodium periodate with a low (catalytic) concentration of potassium permanganate.

An acid salt can be mixed with certain base salt (such as sodium bicarbonate or baking soda) to create baking powders which release carbon dioxide. [10] Leavening agents can be slow-acting (e.g. sodium aluminum phosphate) which react when heated, or fast-acting (e.g., cream of tartar) which react immediately at low temperatures. Double-acting ...

In combination with sodium periodate, OsO 4 is used for the oxidative cleavage of alkenes (Lemieux-Johnson oxidation) when the periodate serves both to cleave the diol formed by dihydroxylation, and to reoxidize the OsO 3 back to OsO 4. The net transformation is identical to that produced by ozonolysis. Below an example from the total synthesis ...
