10022-66-9 Usage
Description
Potassium osmate (VI) dehydrate is an inorganic compound with the formula H4K2O6Os. ISn the VI (6+) oxidation state the compound is a diamagnetic purple salt contains osmium. It is soluble in water and slowly decomposes in aqueous solution. Potassium osmate (VI) dehydrate is insoluble in ethereal and alcoholic solvents.
Preparation
Edmond Fremy first prepared potassium osmate (VI) dehydrate in 1844 by reducing perosmates using alcohol.
2OsO4 + C2H5OH + 3 KOH → CH3CO2K + 2 K2[OsO2(OH)4]
Applications and Reactions
Potassium osmate (VI) dehydrate is used as a catalyst in the dihydroxylation of cyclic internal alkenes such as lactams, 1,2 dioxines dihydrothiophenes and hexahydropyrans. The resulting diols from such reactions have been used in the preparation of various carbohydrate and similar molecular scaffolds. Potassium osmate (VI) dehydrate iss also used in the development of an asymmetric dihydroxylation methodology targeting heteroaromatic acrylates.
Chemical Properties

Check Digit Verification of cas no
The CAS Registry Mumber 10022-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,2 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10022-66:
(7*1)+(6*0)+(5*0)+(4*2)+(3*2)+(2*6)+(1*6)=39
39 % 10 = 9
So 10022-66-9 is a valid CAS Registry Number.
