Today’s Reaction Friday is about the Friedel Crafts acylation of benzene and other aromatics, an important example of electrophilic aromatic substitution. One thing I forgot to say at the bottom is that there’s several different ways of showing how the acyl halide is activated by Lewis acid – the convention I drew is common, but [...]

Today’s video is about the formation of acetals from aldehydes and ketones, an important method for the protection of the carbonyl group. One thing I forgot to mention in the video is that the reaction is an equilibrium – choosing alcohol as the solvent ensures that the equilibrium will be driven towards formation of the [...]
