Formation of N-phenyl substituted hydroxamic acids in the reaction of formaldehyde with substituted mtrosobenzene is strongly catalysed by Fe3+ ions, which stabilize the transition state for the rate-controlling proton transfer from the carbon of nitrosocarbinolic cation intermediate leading to the product, hydroxamic acid
Fe 3+离子强烈催化甲醛与取代的亚硝基苯反应中N-苯基取代的异羟肟酸的形成,从而稳定了用于控制速率的质子从亚硝基碳氢化合物阳离子中间体的碳转移到最终产物羟肟酸的过渡态。酸
