I would like to gain insight about Diels–Alder reactions. which compound among these are more suitable for Diels–Alder reactions?

What two kinds of unsaturated compounds are used in a Diels Alder reaction, and what properties do they need to have?

I need a strong electrophile compound containing halogen. What are your suggestions?

The dienophile should have one or more electron withdrawing groups, but they don't have to halogens.

The halogens may be welcome in a subsequent step, though. Chlorides are also cheap and mass available.
