Prenylsurfactants [(CH3)2C═CH(CH2)nSO3– Na+ (n = 4, 6, or 8)] were designed to probe the “ene” reaction mechanism of singlet oxygen at the air–water interface. Increasing the number of carbon atoms in the hydrophobic chain caused an increase in the regioselectivity for a secondary rather than tertiary surfactant hydroperoxide, arguing for an orthogonal alkene on water. The use of water, deuterium oxide
Prenylsurfactants [(CH 3)2 C = CH(CH 2)ñ SO 3 -的Na +(Ñ = 4,6,或8)]被设计为探测单线态氧的“烯”反应机理在空气-水界面。疏水链中碳原子数目的增加导致仲(而不是叔)表面活性剂氢过氧化物的区域选择性增加,这是因为在水上存在正交烯烃。使用水,氧化氘和H 2 O / D 2O混合物有助于区分均质溶液条件的机械替代方案,包括在氢过氧化物形成步骤中π键的去湿和不对称的过氧化物过渡态的润湿。异戊二烯表面活性剂和光反应器技术允许一定程度的界面控制液体载体上的加氢过氧化反应,其中氧化剂(空气中的1 O 2)以气体形式输送。
