The frontier molecular orbital of 5-phenylcyclopentadiene was predicted on the basis of the orbital mixing rule to deform to favor the Diels–Alder reaction in a syn contrasteric manner. The prediction was substantiated experimentally by the reactions of 5-methyl-5-phenylcyclopentadiene with dienophiles to afford the syn attack products, exclusively.
的前沿分子轨道5-苯基环戊二烯的预测轨道混合规则变形的基础上,以有利于在该Diels-Alder反应顺式contrasteric方式。该预测通过5-甲基-5-苯基环戊二烯与亲双烯体的反应在实验上得到证实,专门提供了顺式攻击产物。
