Question

Question: Draw a stepwise, detailed mechanism for the following reaction.

Short answer

Answer

Step-by-step solution

[4+2] cycloaddition reaction

The electrocyclic addition reaction between a four-pi system (diene) and a two-pi system (dienophile) is referred to as the [4+2] cycloaddition reaction.

All [4+2] cycloaddition reactions are thermally feasible.
