In this particular reaction I spelled out the trick to jot down the product or service of knoevenagel Reaction & Reformatsky response with element system. A Knoevenagel condensation is often a nucleophilic addition of the active hydrogen compound to the carbonyl group accompanied by a dehydration response through which a molecule of h2o is removed (hence condensation). The merchandise is usually an α,β-unsaturated ketone (a conjugated enone).
