Organic Chemistry: An Acid—Base Approach
The reaction of cyclohexene and osmium tetroxide, for example, gives osmate
ester 130 with a cis relationship of the two C–O bonds in the five-membered ring.
In the presence of NaHSO3, the osmate ester is converted to the diol, 124.

These ligands were presumed to immobilize the osmate [OsY'(OH)^] by chelation
. The resulting chelated lower-valency osmium component would thus be
responsible for the subsequent accumulation of the osmate-cyanide complexes ...

Organic Chemistry with Biological Applications
Instead, it takes place through an intermediate cyclic osmate, which is formed in a
single step by addition of OsO4 to the alkene. This cyclic osmate is then cleaved
using aqueous sodium bisulfite, NaHSO3. A cyclic osmate intermediate cis-1 ...
