用DMF中的苯酚钾处理α位不带氢的内取代的9-溴蒽在亲核取代和还原脱卤之间引起竞争。带有电子吸引基团1c(Br),1e(CN)和1f(NO 2)的衍生物基本上通过取代反应生成酚醚2,而与未活化的溴化物1a(H),1b(C 6 H 5))和1d(OC 6 H 5),主要反应是还原为蒽3 这应该是由电子转移引起的。

heterogeneous reductions of the endoperoxides 9,10-diphenyl-9,10-epidioxyanthracene (DPA-O2) and 9,10-dimethyl-9,10-epidioxyanthracene (DMA-O2) were investigated, and they were found to undergo a dissociative electron-transfer reduction of the O-O bond to yield a distonic radical anion, with no evidence for C-O bond dissociation. A number of thermochemicalparameters for each were determined using Savéant's
The present invention relates to the use of certain organic compounds comprising fused aromatic compounds in organic electronic devices, in particular electroluminescent devices.

potassium phenoxide in DMF gives rise to a competitionbetweennucleophilicsubstitution and reductivedehalogenation. Derivatives carrying electron attracting groups, 1c (Br), 1e (CN) and 1f (NO2), react essentially by substitution leading to phenolic ethers 2, whereas with non-activated bromides, 1a (H), 1b (C6H5) and 1d (OC6H5), the main reaction is a reduction to anthracenes 3 which should arise from

The first example of an O-neophyl-type rearrangement in a distonic radical anion was found in the electron transfer induced dissociative reduction of 9,10-diphenyl-9,10-epidioxyanthracene.
