Abstract A preparation in ‘dry media’ of phenothiazine derivatives by thionation of diphenylamines using microwave-activation is presented. This method allowed the preparation of 2,4,6,8-tetra-tert-butyl-10H-phenothiazine 2e, the first 2,4,6,8-tetra-substituted derivative of this heterocycle, practically inaccessible by other thionation procedure.
摘要 介绍了一种在“干燥介质”中通过使用微波活化二苯胺硫化作用制备吩噻嗪衍生物的方法。该方法允许制备 2,4,6,8-四-叔丁基-10H-吩噻嗪 2e,这是该杂环的第一个 2,4,6,8-四取代衍生物,其他硫化过程几乎无法获得。
