Ramberg-Bäcklund Reaction
Let's hit one more olefination reaction, the Ramberg-Bäcklund reaction. This one involves an extrusion of sulfur dioxide to yield an olefin in intramolecular fashion. This is an example of a cheletropic reaction. Let's check out the...

The 18 Electron Rule for Transition Metal Complexes
Ok, so we understand how ligands bond to metals to form transition metal complexes, but how many ligands will fit? Well, remember the octet rule from general chemistry? There is a similar concept that we can apply here, which is called...

What Is The Carbon Cycle - Part 2
Watch part 2 of the videos on the Carbon Cycle, as a part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

Organolithium Reagents
We've seen one organometallic reagent before, the Grignard reagent. That had magnesium in it. Well now let's learn another! Organolithium reagents are commonly used, so let's see what they do.

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...
