④Distillation for 45min should provide the 12mL of cyclopentadiene
⑤continued distillation for half hour gives a total of about 20mL of monomer
주의) 얻어진 monomer는 실온에서 다시 dimer가 되기 때문에 cracking을 하는 동안 실험 2를 미리 준비 해놓고 실험 1에서 얻은 monomer를 바로 쓸 수 있게 한다.
① Place 6g of maleic anhydride in a 1
Background
Diels-Alder Reaction
: An addition reaction between a 1,3-diene and an alkene called a dienophile, to form a new six-membered ring.
1) The reaction forms two σ and one π bond in a six-membered ring.
2) The reaction is initiated by heat.
3) All bonds are broken and formed in a single step. (concerted reaction)
4) The diene must react in the s-cis conformation
5) Electron
