inherent weakness of the N,O bond, leading to products of isomerization and rearrangement. In a third instance, methyl translocation from oxygen to sulfur occurred to furnish a heteroaromatic N-oxide at the expense of a cross conjugated π-system. Consistent X-ray crystallographic data sets served as a basis for electronic structure method assessment in order to model aspects relevant to structure and decomposition
合成、光谱和结构研究提供的证据表明,纯 3-烷氧基-4-(对氯苯基)-1,3-噻唑-2(3H)-硫酮 (CPTTOR) 曾被开发用作储存的烷氧基自由基前体并按需使用,显示出背景反应性。这些转化的选择性由 O-烷基取代基的性质决定。两种途径反映了 N,O 键的固有弱点,导致异构化和重排产物。在第三种情况下,发生了从氧到硫的甲基易位以牺牲交叉共轭 π 系统为代价提供杂芳族 N-氧化物。
