parameters have been determined (a) for the solvolysis of 1-,3- and 4-chloromethylpyrene in different solvents (Table 11) and (b) for the S,2 reaction of 1- and 4-chloromethylpyrene with KI in acetone (Table IV). Taking into account previous results, it is shown that 3-chloromethylpyrene has an apparently abnormally high rate constant in solvolysis reactions.
确定了ARRHENIUS参数(a)用于在不同溶剂中溶剂化1-,3-和4-
氯甲基py(表11),以及(b)确定1-和4-
氯甲基py与KI在
丙酮中的S,2反应(表IV)。考虑到先前的结果,表明3-
氯甲基py在溶剂分解反应中具有明显异常高的速率常数。
