Organocuprates (Gilman Reagents)
We've seen organometallic reagents featuring magnesium, as well as lithium, so how about copper? These are called organocuprates, or sometimes Gilman reagents. What do they look like? How do we make them? What do we do? Let's take a look!

Heterocycles Part 1: Furan, Thiophene, and Pyrrole
We've mentioned heterocycles before. They are cyclic molecules where one or more atoms in the ring are not carbon. Typically these involve oxygen, nitrogen, and sulfur. But there are so many different heterocycles. Different sizes, some...

Recognizing Chemical Reactions
This video explains the concept of chemical reactions and provides clues to recognize when they occur. It highlights examples such as color changes, bubbling, heat or light production. This video is part of the 7-part series, Chemical...

The Haloform Reaction
Once again, we will be interested in learning about reactions that break carbon-carbon bonds, as this will allow us to perform necessary transformations on substrates. The haloform reaction is one such reaction, and it is commonly used...

Carbenes Part 2: Cyclopropanation, C-H Insertion, and the Bamford-Stevens Reaction
In the previous tutorial we learned about carbenes. So now that we understand their properties, we are ready to learn about what we can do with them. Three major uses of carbenes involve cyclopropanation, C-H insertion, and the...

How To Measure Loss Of Mass In A Reaction
In this video, we’re going to learn about the loss of mass in a chemical reaction, how it happens and why we measure this. The total MASS of reactants will be the same as that of the products, as mass is always conserved in a chemical...

Beckmann Rearrangement
Have you ever had a ketone and wished you had an amide instead? Not to worry! The Beckmann rearrangement is the solution to your problems. Check out this nifty reaction where we get an oxime and then get an alkyl group to migrate. We can...

Diazomethane Synthesis and Applications (Arndt-Eistert Homologation)
In learning about carbenes, we discovered the importance of diazomethane. So it will be a good idea to learn how to make this molecule, as well as some other things we can do with it, including something called the Arndt-Eistert...

Baeyer-Villiger Oxidation
We just learned how to make lactams out of cyclic ketones, is there a similar way that we can make lactones? There is! Try the Baeyer-Villiger oxidation. This is another one of those rearrangement type of reactions, only this time we are...

Heterocycles Part 2: Pyridine
In the previous tutorial, we learned about some five-membered aromatic heterocycles. Those were furan, thiophene, and pyrrole. Now let's learn about a six-membered one, pyridine. This one is ubiquitous in nature, so let's get the scoop...
