| 11. | This uses a catalytic loading of osmium tetroxide which is regenerated in situ by the periodate.
|
| 12. | Osmium tetroxide is rapidly reduced to relatively inert compounds by polyunsaturated vegetable oils, such as corn oil.
|
| 13. | Manganese is also used in dihydroxylation and is often chosen when osmium tetroxide methods yield poor results.
|
| 14. | Osmium tetroxide boils at 130 �oxidizing agent.
|
| 15. | Osmium tetroxide has been used in fingerprint detection and in staining fatty tissue for optical and electron microscopy.
|
| 16. | Since osmium tetroxide is expensive and toxic, other metals have been used to prepare vicinal diols from olefins.
|
| 17. | It may be prepared by the reaction of osmium tetroxide with hydrobromic acid, followed by zinc and cyclopentadiene.
|
| 18. | It involves the local administration of osmium tetroxide ( OsO 4 ), which is a highly toxic compound.
|
| 19. | Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact.
|
| 20. | Prior to this method, use of stoichiometric amounts of the toxic and expensive reagent osmium tetroxide was often necessary.
