buffer-independent reaction involves rate-limiting heterolyticbondfission of the diazoic acid to yield a diazonium ion intermediate, and a similar mechanism is indicated for the other two compounds. General acid catalysis of the decay of the diazoic acids at pH < 7 is observed, and it is concluded that the reaction involves rate-limiting N−O bond cleavage of the diazoic acid that is concerted with
研究三种 (Z)-2,2,2-三氟-1-芳基乙烷重氮酸盐在 25 °C 时在水性介质、4% 2-丙醇体积、离子强度 1 M (NaClO4) 条件下的衰减动力学范围 4-13,以及检测氘掺入溶剂产品的实验结果。在未取代的化合物的情况下得出结论,不依赖缓冲液的反应涉及重氮酸的限速异裂键裂变以产生重氮离子中间体,并且其他两种化合物具有类似的机制。观察到在 pH < 7 时重氮酸衰变的一般酸催化作用,并得出结论,该反应涉及重氮酸的限速 N-O 键断裂,这与催化剂对离开氢氧根离子的质子化一致.
