An investigation of the catalytic effect on vanadium bromoperoxidase (VBrPO, from Corallina officinalis) on the oxidation of a series of prochiral sulfides by hydrogen peroxide, revealed that substrates having a cis-positioned carboxyl group are oxidized rapidly, giving the sulfoxide in >95% e.e. The pH-rate profile shows a typical sharp sigmoidal curve, indicative of a deprotonation event at around

Depending upon conditions, a variable amount of oxidation of the hydroxymethyl substituent into an aldehyde was observed to accompany deoxygenation. Analysis of the photoproducts indicated the deoxygenation occurred by at least two different pH-sensitive mechanisms. Underbasicconditions, photoinduced electron transfer yielding a hydroxysulfuranyl radical that decomposed by heterolytic S-O cleavage was thermodynamically
使用原子氧 (O((3)P)) 作为水中的强氧化剂一直缺乏简便、有效的来源。已建议将芳族亚砜光脱氧到有机溶剂中的相应硫化物,以低量子产率生产 O((3)P)。4,6-二羟甲基二苯并噻吩 S-氧化物和 2,8-二羟甲基二苯并噻吩 S-氧化物在水中的光解导致脱氧的量子产率明显高于有机溶剂。根据条件,观察到羟甲基取代基氧化成醛的变化量伴随脱氧。光产物的分析表明,脱氧作用是由至少两种不同的 pH 敏感机制引起的。在基本条件下,光致电子转移产生羟基硫烷基自由基,通过异裂 SO 裂解分解在热力学上是可行的。随着溶液的 pH 值降低,预计光致电子转移的热力学将变得越来越不利。因此,在中性和酸性 pH 值下,怀疑 SO 键断裂机制。观察到的光脱氧量子产率的增加与伴随 SO 键断裂的电荷分离一致。在有氧条件下烯烃的氧化裂解表明 O((3)P) 是在这些条件下的光解过程中产生的;然而,可能会形成离散的 O(*-)/HO(*),尤其是在低
