Nef Reaction (Introduction to Umpolung Chemistry)
The Nef reaction is a good way to convert nitronates into carbonyl compounds. This is a technique that can be incorporated into a strategy called "Umpolung", which refers to a reversal of polarity, such that upon converting from the...

Practice Problem: Synthesis Challenge
We've got a target molecule to synthesize, and we have to start from benzene and other reagents of three carbons or less. How are we gonna do this? Think about the reactions you know, especially some electrophilic aromatic substitution,...

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...

Organometallic Reactions Part 2: Oxidative Addition
In addition to ligand exchange, another common organometallic reaction is oxidative addition. This commonly occurs with metals that have stable oxidation states that are two apart. Let's explore some examples of different stypes of...

Organometallic Reactions Part 5: Nucleophilic/Electrophilic Attack on Ligands
Reactions that occur on the ligands themselves are quite common. Let's look at two common types of ligand reactions: nucleophilic and electrophilic attacks. Which types of ligands that are susceptible to these attacks and what happens?

Polynuclear Transition Metal Complexes
In previous videos, we have discussed complexes with a single metal center, but in this video we will focus on polynuclear transition metal complexes. Let's go through a couple examples and review how to check that the 18-electron rule...

Visualizing DNA in Virtual Reality
We've learned a lot about DNA, but sometimes the representations of DNA that we use to talk about it are not especially accurate. Everyone knows the popular image with the ladder rungs, but let's really get in there and visualize DNA in...

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...

Fischer Esterification and Saponification
How do we go from carboxylic acids to esters? Fischer esterification! How do we go from esters to carboxylic acids? Saponification! Let's get a closer look at these complementary processes now.
