- Compounds P and Q can undergo a Diels-Alder reaction to form two regioisomeric products R and S as shown in Figure 5. OMe O C8H12O2 R C8H12O2 S Figure 5 Draw the chemical structures of regioisomeric compounds R and S. Using possible resonance contributors of P and Q predict which of the two regioisomers will be favoured in the reaction. Using curly arrows, draw the mechanism for the reaction of P and Q to form the dominant regioisomer you have predicted in your answer to part (ii) above.arrow_forwardPredict the product(s) of the following Diels-Alder reaction. Include stereochemistry if appropriate.arrow_forwardCyclobutane reacts with bromine to give bromocyclobutane, but bicyclobutane reacts with bromine to give 1,3-dibromocyclobutane.
