Benzyl isopropyl ether also forms CCT complex with oxygen on the benzene ring like phenyl isopropyl ether, but it is easy to oxidize since charge transfer and 〓 transfer may occur at the methylene group adjacent to the benzene ring, which result in the oxidation of the methylene group.(4) The 〓-CCT complex and the initial dark oxidation mechanism of poly were studied.

虽然苄基异丙醚也以苯环与O〓形成CCT复合物，但它却容易发生暗氧化，这是由于与苯基相连的是亚甲基，此时电荷转移发生在苯环与亚甲基之间，引起亚甲基的氧化，而不是异丙基的氧化。

It was confirmed that the 〓-CCT of phenyl isopropyl ether is formed on the benzene ring rather thanon the etheroxy bond. The 〓-CCT complex is not strong enough to induce charge transfer and converts to CTC because the isopropyl group is separated from the benzene ring by oxygen atom. As a result,〓 can not transfer from isopropyl to form radical in cage. Therefore phenyl isopropyl ether is difficult to undergo dark oxidation.

这是由于苯基异丙醚和异丙醚形成O〓-CCT的部位不同，苯基异丙醚的O〓-CCT形成在苯环上，与异丙基相隔一个氧原子，不足以诱发异丙基电荷转移而转化为CTC，也就不能有氢质子转移和笼式自由基的形成，因此难于发生暗氧化反应。
