| 11. | Another example is hydroboration reaction, in which " diborane " adds to an alkene.
|
| 12. | Hydroboration proceeds in an antimarkovnikov manner.
|
| 13. | Borane makes a strong adduct with triethylamine; using this adduct require harsher condition in hydroboration.
|
| 14. | These solutions are used for reductions and hydroboration, reactions that are useful in synthesis of organic compounds.
|
| 15. | Alkyne hydration with this same molecule can occur through hydroboration as well without the presence of a catalyst.
|
| 16. | Organoboron compounds are important reagents in organic chemistry enabling many chemical transformations, the most important one called hydroboration.
|
| 17. | When catecholborane is treated with an alkyne, usually a terminal alkyne, through hydroboration a trans vinylborane is formed.
|
| 18. | This type of reaction has promoted research on hydroboration because of its mild condition and a wide scope of olefins tolerated.
|
| 19. | Whereas uncatalyzed hydroboration using HBcat leads to reduction of the carbonyl group, the catalyzed version is selective for the alkene.
|
| 20. | To account for the high regioselectivity of catalyzed hydroboration, Hayashi proposed a mechanism involving a ? 3-benzylrhodium complex.
