โฆ Synopsis
find that osmium tetroxide, OsO4, is converted into a salt by an aqueous solution of sodium hydroxide, in which the concentration of that salt ranges between 0.0277 and 0.0587 normal. This salt is a derivative of perperosmic acid, H~OsOs. Previous investigators have expressed a difference of opinion as to the acidforming properties of this oxide.

Thymine and its derivatives react rapidly in aqueous solution with osmium tetroxide and pyridine to form stable bis(pyridine) osmate esters. We have studied these esters with the following pyrimidines: thymine, thymidine, thymidine-5'-phosphate, and uracil, using pyridine, 3-picoline, 3-chloropyridi
Osmium tetroxide catalyzed hydroxylation of sterically hindered olefins proceeds efficiently with trimethylamine N-oxide as oxidizing agent in the presence of pyridine.
The MCD spectrum of OS04 in argon and nitrogen matrices at CJ 20 K has been measured and is remarkably similar the first band of MrtOz in KI04 at 4.2 K. From this it is concluded that there are two e!ectronic origins in the region 30 000-39 000 cm-' and the spectrum of 0~04 is reassigned accordingly
