Diels–Alder reaction, an Uncommon card
In organic chemistry, the Diels–Alder reaction is a chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene derivative.

Diels–Alder reaction quiz: 3 questions
Three questions on the Diels–Alder reaction card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Consequently, it is a powerful tool, widely applied to introduce chemical complexity in the ______ of natural products and new materials.
Answer
synthesis. Consequently, it is a powerful tool, widely applied to introduce chemical complexity in the synthesis of natural products and new materials. From the Diels–Alder reaction article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Induced pluripotent stem cell. Induced pluripotent stem cell 85 · Diels–Alder reaction 81 · Concretion 78 · Lanthanum 75 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Lanthanum. Lanthanum 91,000 · Diels–Alder reaction 62,000 · Miss Universe Philippines 2024 45,000 · Computational chemistry 32,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is the prototypical pericyclic reaction with a concerted mechanism, specifically, it is a thermally-allowed [4+2] cycloaddition with Woodward–Hoffmann symbol [π4s + π2s].
- Simultaneously constructing two new carbon–carbon bonds, the Diels–Alder reaction reliably forms six-membered rings with good regio- and stereochemical control.
- Consequently, it is a powerful tool, widely applied to introduce chemical complexity in the synthesis of natural products and new materials.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Diels–Alder reaction article was read about 62,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 81 and blocks with 90: each hit it takes is cut by 36 %.
How to get Diels–Alder reaction
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
