What are the reagents for the reduction step of oxymercuration reduction
NaBH4 and NaOH
What are the reagents for hydrogenation
Pt and H2
What are the products for halohydrin synthesis
X adds to the less substituted carbon, and OH adds to more substituted carbon
What are the products for acid catalyzed hydration
OH adds to the more substituted carbon, and H adds to the les susbstituted carbon
What are the products for hydroboration oxidation
- Intermediate: B in the middle of 3x new alkane
- OH adds to less substituted carbon, H adds to more substituted carbon
