Diketones. The Sharpless procedure for oxidation of alkenes with NaIO catalyzed by Ru02 (11,462-463) is equally efficient for oxidation of alkynes to 1,2-diones. In fact, alkenes and alkynes react at a similar rate, but ether, epoxide, and ester groups are stable to the reagent. A 1-silylacetylene is oxidized to an acylsilane. Yields are moderate to high.1... 

V. S. Letokhov Prof. Gerber, can we exploit the analogy between the asymmetric fragmentation process (Nai3 — Naio + Na3) and the fission of nuclei ... 

For each crystal, reflections from two intensity-equivalent regions of reciprocal space (hki, hSkS t, and khi, k h S ) were examined using the 0-26 scan technique. (For Ba]Naio-A, the two regions examined were hkl and hik.) Each reflection was... 

Periodic Acid.—The oxidation of iodic acid to periodic acid is accomplished by means of a solution of sodium hypochlorite it is easier to dissolve iodine in a solution of sodium carbonate, when hypoiodite is formed, and to saturate the solution with chlorine. The iodate at first formed is converted into the periodate NaIOs. Aq +... 

This salt, in which iodine is in a +6 oxidation state, results from heating Na2H3IOe at 120 to 180°C.101 Using X-ray diffraction, magnetic susceptibility, and infrared absorption, the chemical individuality of the salt was established i.e., it is not a mixture of NaIOs and Na3I05. The compound is stable up to 370°C, but its decomposition products were not identified. 

NIOSH REL TWA 2.5 mg(F)/m3 DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE This material is very toxic to humans by ingestion between 1 teaspoonful and 1 ounce may be fatal. Inhalation of dust may cause irritation to respiratory tract. Skin contact may result in irritation and ulceration eye contact may cause burns. To fight fire, use water, foam, CO2, dry chemicals. When heated to decomposition it emits toxic fumes of F" and NaiO. See also FLUORIDES and HYDROFLUORIC ACID.
