Short Films on Chemistry Experiments
Digitally recorded video sequences of chemistry experiments allow students to closely observe the experimental procedure through repeated playback, making the process easy and flexible in terms of time. The short videos can be used by students for independent preparation and follow-up work, or they can be shown in lectures and lab sessions where the facilities do not allow for conducting the experiments on site.

Brief explanation of radical side-chain halogenation using toluene as an example:
Depending on the reaction conditions, aromatic compounds can be brominated either at the ring or in the (aliphatic) side chain. Under UV radiation and/or high temperatures, bromination occurs in the side chain (SSS rule: Sun (UV radiation), boiling heat, side chain).
In the presence of a catalyst (e.g., FeBr₃) and at low temperatures, ring substitution occurs (KKK rule: catalyst, cold, ring substitution).
Brief explanation of the Diels-Alder reaction:
The Diels-Alder reaction is a [4+2] cycloaddition. A typical example is the reaction of maleic anhydride with cyclopentadiene.
