Diels-alder cycloaddition reactions the diels-alder reaction requires diene and dienophile reactants which combine to form a product called the adduct. Diels-alder reaction the [4+2]-cycloaddition of a conjugated diene and a dienophile (an alkene or alkyne), an electrocyclic reaction that involves the 4 -electrons of the diene and 2 -electrons of the dienophile. The diels-alder reaction is an organic chemical reaction (specifically, a [4+2] cycloaddition ) between a conjugated diene and a substituted alkene , commonly termed the dienophile , to form a substituted cyclohexene system it was first described by otto diels and kurt alder in 1928, for. The diels-alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as a.
