OCHEM2.1

• Turns into a Keytone. removes two H's.
• 1 from alpha Carbon and 1 from the OH.
• the elminiation becomes a bond between the c and o.
• now it is a double bond.

very broad; around 3600-3200

takes 2 H's. one from OH and one from alpha carbon (there's 2 H's on the alpha) those will form a bond.

Breaks in Half (literally) and add an O at the end of the bonds.

stereocenter when formed

alkenes to epoxide. top and bottom side attack.

**the groups stay in the same place (stereocenter wise, no changes in the 3D) since it is top and bottom attack, the only thing will change is the epoxide itself. that will go on top or bottom.(plain stereo)

2250

if the triple bond is at the end, the C-H bond turns into CO₂

• triple bond breaks into a double bond with O
• and a bond with an OH.

• Keep OH and the 2H's turn into C=O.
• *Cr- Creep (keep OH)

Alkene with OH turns into epoxide with OH.

• OH needs to be on the Right Hand corner.
• (+)Det is below
• (-)Det is above.

Any product OH will be going away. All products OH will be going away. Below or above attacks should be in plain stereo. because OH is going away and what other product will be going towards. leaving plain to use.

Adding 2H's to any double or triple bonds. what for stereocenters.

Double bond breaks open and will turn into 2 OH bond.

1650

3500-3200

Breaks in Half and at the end of the double bonds will be an O. so c=o

anti OH

3000-2850

1600-1500

2250

3150-3000

If it is not reacting with epoxide then it will only remove the alkyl halide group. cl would become h

C=O and C-OH bond arm formed.

Will only, ONLY break a triple bond into a double bond.

• H- leaves from LiALH4
• attacks the less sub.
• O is on more sub. H2o adds H to O. becomes OH.

2 stereocent after formed

3300

2H's turns into C-O bond. which means C-O will be a C=O.
