Overview:
Osmium tetraoxide (OsO4) is a commonly used reagent in organic chemistry. It is known for its high reactivity and ability to form stable complexes with a wide range of organic compounds. In this answer, we will discuss the correct statements about OsO4, which are options A, B, and C.
Explanation:
A. OsO4 is commonly known as osmic acid:
Osmic acid is the common name for OsO4. It is a yellow crystalline compound that is highly toxic and has a pungent odor. It is commonly used in organic synthesis for various reactions, including dihydroxylation of alkenes and oxidative cleavage of diols.
B. OsO4 reagent always attacks on the less hindered side of the olefinic bond:
When OsO4 reacts with an alkene, it undergoes a syn addition reaction, meaning it adds to the same face of the double bond. The addition of OsO4 occurs on the less hindered side of the olefinic bond. This regioselectivity is due to the steric effects of the bulky OsO4 molecule. The less hindered side of the double bond allows for better approach of the reagent, resulting in the formation of a cyclic osmate ester.
C. OsO4 is most often used for anti-hydroxylation of alkenes:
Osmium tetraoxide is commonly used for the dihydroxylation of alkenes. During this reaction, two hydroxyl groups (-OH) are added across the double bond of the alkene, resulting in the formation of a vicinal diol. This reaction proceeds in an anti-addition manner, where the two hydroxyl groups are added to the opposite faces of the double bond.
Conclusion:
In conclusion, the correct statements about osmium tetraoxide (OsO4) reagent are:
A. OsO4 is commonly known as osmic acid.
B. OsO4 reagent always attacks on the less hindered side of the olefinic bond.
C. OsO4 is most often used for anti-hydroxylation of alkenes.
