Scientists have shown off what can be described as the world’s smallest electric car – made of a single, carefully designed molecule. The molecule has four branches that act as wheels, rotating when a.

Once the "nucleophilic aldehyde" synthon is formed, whether as a cyanohydrin or stabilized by a thiazolium ylide, the reaction can proceed down two pathways. The faster pathway is self-condensation with another molecule of aldehyde to give benzoin products. However, benzoin condensation is completely reversible, and therefore does not interfere with product formation in the Stetter reaction.
