What happens when a hindered dialkylborane is added to a terminal alkyne?
An aldehyde is formed.
What happens when you add an HX to an Alkene?
Your product is a haloalkane.
What happens to an alkene during an acid catalyzed hydration?
An alkene is converted to an alcohol.
What happens when you add an X2 to an alkene?
You convert the alkene into a vicinal dihalide.
How do alkenes get converted to halohydrins?
The addition of an HX2 in the presence of a solvent.
What does an oxymercuration-reduction reaction do to alkenes?
They convert alkenes to alcohols. No rearrangements are possible here like there were in acid catalyzed hydration.
What are the reagents used in oxymercuration oxidation?
1.Hg(OAc)2 ,H2O 2. NaBH4
What happens to alkenes during hydroboration oxidation?
They get turned into alcohols with non-markovnikov regioselectivity.
What happens when you add OsO4 to an alkene?
You get a glycol with syn stereoselectivity.
What happens during ozonoanalysis?
The C=C double bond is cleaved into two C=O double bonds
What are the reagents in catalytic reduction?
H2 and a transition metal catalyst.
What does a catalytic reduction do to an alkene?
It turns the alkene into an alkane with syn stereoselectivity.
What does Hydroboration/Oxidation of an alkyne create?
It creates an enol that is in equilibrium through keto-enol tauteromerism, with a ketone.
What does a terminal alkyne and a strong base yield?
It yields an acetylide salt.
What happens when you treat an alkene with a HX2?
You get a dihaloalkane.
What happens when you treat an alkyne with one X2? What happens when you add the second one?
You get an E. Dihaloalkane with the first. After the second you get a tetrahaloalkane.
What does addition of 2 HX to an alkyne yield?
A geminal dihaloalkane.
