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。
