sulfoxylates (7b, 4-NO(2); 7c, 4-Cl; 7d, 4-CH(3)O, 7e: 4-CH(3)) are reported. The unexpected stability of 7b has permitted the first X-ray determination at room temperature of a sulfoxylate. The thermal isomerization of sulfoxylates 7b-c to sulfinates 8b-c was studied in different solvents (toluene-d(8), CDCl(3), and CD(3)CN) and interpreted as a concerted unimolecular process following first-order kinetics
据报道制备了二苄基亚砜7a和4-取代的苄基亚砜(7b,4-NO(2); 7c,4-Cl; 7d,4-CH(3)O,7e:4-CH(3))。7b的出乎意料的稳定性使它在室温下可以进行第一次X射线测定。在不同溶剂(甲苯-d(8),CDCl(3)和CD(3)CN)中研究了亚硫酸盐7b-c到亚磺酸盐8b-c的热异构化,并解释为遵循一阶动力学的一致单分子过程。
