  摘要：

  本文提出了一种评估烷化剂在水介质中对吡啶的化学选择性的简单方法。该分析方法包括评估吡啶在水性缓冲液（pH 值为 6.0）中的相对季铵化速率和水解速率，即评估在含有大量过量吡啶的磷酸盐缓冲液中，给定烷化剂对吡啶的氮功能和氧功能进行竞争性亲核攻击时对吡啶的化学选择性。Spy 一词暂时定义为 log {(N/(1-N))×[H2O]/[py]}，其中 N 是在完全消耗给定的烷化剂后吡啶季铵化所消耗的摩尔分数，[H2O]和[py]分别是水和吡啶的浓度。在 37°C 含 4% 丙酮的 1/15 M 磷酸盐缓冲液（pH 值为 6.0）中，Spy 与 Swain 和 Scott 定义的底物常数（s）呈线性相关：s=0.163Spy+0.209（r=0.995，n=8）。本文简要讨论了化学选择性与反应温度和介质中丙酮含量的关系。
