Approximate rateconstants for intermolecular additions of alkylradicals to phenylsulfonyl oxime ethers (2a and 2b) have been determined to be ka=9.6×105 M−1s−1 at 25 °C for 2a and ka=7.3×104 M−1s−1 at 60 °C for 2b, indicating that the additions are fast and highly efficient processes. The kinetic data have been confirmed by two competition experiments.
已确定在25°C下2a和k a = 7.3×10 4的分子间烷基向苯磺酰基肟醚(2a和2b)分子间加成的近似速率常数为k a = 9.6×10 5 M -1 s -1。M -1 s -1在60°C下持续2b,表明添加是快速且高效的过程。动力学数据已通过两次竞争实验得到证实。

ketones, amines, hydroxylamines, and nitriles. We describe the catalytic decarboxylation of aliphaticcarboxylicacids to oxime ethers. With AgNO3 as the catalyst, valuable oxime ethers bearing various substituents could be easily obtained. The broad substrate scope, easy accessibility of aliphaticcarboxylicacids, and mild reaction conditions make this strategy immediately applicable to the synthesis
