Reduction of Esters With DIBAL-H
We know about a lot of different oxidizing and reducing agents that facilitate a variety of different transformations. But we haven't touched upon the precise transformation that can be achieved by diisobutylaluminum hydride, also known...

Practice Problem: Reducing Agents
For this one we need to know the ability of different reducing agents to react with various functional groups.

Professor Dave Explains
Henry Reaction
The Henry reaction is sometimes called a nitroaldol reaction, because it involves the addition of a nitronate salt to a carbonyl compound. This is a great setup for a Nef reaction, which was learned in the previous tutorial. Let's look...

Practice Problem: Ozonolysis Reactions
Ozone isn't just for shielding us from harmful UV radiation! It's a handy-dandy synthetic tool. Try these on for size.
Professor Dave Explains
Practice Problem: Grignard Reactions
Grignards are all over the place! Better make sure we can draw the correct products of Grignard reactions. Try these for practice.
Professor Dave Explains
Practice Problem: Four-Reaction Pathway
We are starting with benzene, we do four reactions, and what do we get? See if you can get the right answer!
Professor Dave Explains
Practice Problem: Crossed Aldol Products
Enolate chemistry is tricky business! You might get more products than you think. Give this one a shot.
Professor Dave Explains
Practice Problem: Oxidizing Agents
For this one we need to know the ability of different oxidizing agents to react with various functional groups, and what functional groups will result.

Ugi Reaction
We just learned about the Passerini reaction, and now it's time to learn a similar one, the Ugi reaction. This is another multi-component reaction that is excellent for generating chemical libraries. To the components of the Passerini...

Cannizzaro Reaction
The Cannizzaro reaction is pretty old, over 150 years old in fact, but it is still an important reaction in organic chemistry. It involves the disproportionation of two equivalents of an aldehyde, meaning one is oxidized to the...

Cleavage of Carbon-Carbon Bonds With Periodic Acid
Just as important as learning reactions that generate carbon-carbon bonds, we need ways to cleave carbon-carbon bonds as well.This is useful for splitting a molecule up into fragments, or transforming a cyclic molecule into a linear...
Curated Video
Just weeks after the death of a Louisiana woman who sued over formaldehyde in FEMA trailers, a house panel looks into the problem today.
