produce ketyl radical anions that dissociated rapidly at room temperature to release carbon-centered radicals and an aromatic phenoxide type anion. In the PET process with benzyl-substituted cyclohexadienones, initiated with triethylamine, the benzyl radicals dimerised or abstracted an H-atom from solvent. In electrochemical reductions, and in reductions with alkali metals in liquid ammonia, the benzyl
制备了几种2-和4-烷基环己二酮,并显示它们接受电子以产生酮基自由基阴离子,所述酮基自由基阴离子在室温下迅速解离以释放出以碳为中心的自由基和芳族酚盐型阴离子。在用三乙胺引发的苄基取代的环己二酮的PET工艺中,苄基使溶剂中的H原子二聚或析出。在电化学还原中以及在液态氨中用碱金属还原时,苄基进一步还原为阴离子。
