Product distribution, total quenching rate (kT), and rate of chemical reaction (kr) with singlet oxygen have been determined for some alkyl, benzyl, α-methylbenzyl, and cumyl sulfides. Their contributions depend on the steric hindering around the sulfur atom. In protic solvents, the sulfoxide is the main product via a hydrogen-bonded persulfoxide. In apolar solvents, intramolecular α-H abstraction
对于某些烷基,苄基,α-甲基苄基和枯基硫化物,已经确定了产物分布,总猝灭速率(k T)和与单线态氧的化学反应速率(k r)。它们的作用取决于硫原子周围的空间位阻。在质子溶剂中,亚砜是通过氢键结合的过亚砜的主要产物。在非极性溶剂中,分子内α-H的抽象会导致C-S键的氧化裂解,效率会有所不同。将硫化物的行为与烯烃和胺的行为进行了比较。
