借助热化学循环估算衍生自异构体 9-苯硫基甲基蒽 (1) 和 10-苯硫基-9-甲基蒽 (2) 的自由基阴离子中所含 C-S 键的强度。由 1 和 2 衍生的自由基阴离子中最弱的 C-S 键的键解离能 (BDE) 分别为 11 和 38 kcal/mol。衍生自苯基硫醚 (3) 和苄基苯基硫醚 (4) 的自由基阴离子中存在的 C-S 键的 BDE 分别约为 1 和 -15 kcal/mol
Estimated with the aid of a thermochemical cycle are the strengths of C-S bonds contained in radical anions derived from the isomeric species 9-phenylthiomethylanthracene (1) and 10-phenylthio-9-methylanthracene(2). Bond dissociation energies (BDEs) for the weakest C-S bonds in the radical anions derived from 1 and 2 are 11 and 38 kcal/mol, respectively. BDEs for C-S bonds present in radical anions derived from phenyl sulfide (3) and benzyl phenyl sulfide (4) are about 1 and -15 kcal/mol, respectively
