Products of this chemical reaction often undergo an additional elimination resulting in conjugated systems.  
Products of this chemical reaction often undergo an additional elimination resulting in conjugated systems.  Generally using either sodium or potassium hydroxide as a catalyst, it results in an intermediate alkoxide  from a nucleophilic enolate's addition to a carbonyl group in either ketones or aldehydes before reaching the final beta-product, which is often altered by dehydration. For ten points, name this condensation reaction  whose name combines that of its two final products and which may have been discovered by Aleksandr  Borodin.
