cyclopentadiene:

Let’s talk about one of my favorite reactions: the benzoin condensation! This reaction is formally a disproportionation reaction: the carbonyl carbon goes from a +1 state in the starting material to 0 and +2 in the hydroxyl and new carbonyl carbon, respectively.

At first glance, this reaction appears to happen by simple nucleophilic addition to one of the carbonyls. However, this is not the case at all; benzaldehyde is not readily deprotonated, with a pKa close to 15. In fact, because of the carbon-oxygen double bond, that carbon is highly electrophilic! How does this reaction proceed? The answer lies in the cyanide catalyst. Let’s examine the mechanism more closely to figure out what exactly goes on…

Everyone knows oil doesn’t mix with water. In chemistry we also use this to purify our compounds! The top layer is oily/non-polar (ethyl acetate) while the bottom is water/DMSO. My product should be oily so it should go in the top layer!

This pretty yellowish stuff is some highly toxic and hazardous organomercuric reagent what was made in situ from some mercury(II)-acetate and an alkene.
Real, sweet organometallic chemistry(:

DNA codons to Amino Acids!
Really cool visual, but may be a little to busy for learners.
