The reaction of substituted benzothiazine sulphoxides with Ac2O under reflux leads by an elimination reaction to a sulphenic acid derivative which undergoes subsequent addition to the generated double bond if the nitrogen is tertiary but is trapped as a cyclic sulphenamide by a secondary nitrogen.
取代的苯并噻嗪亚砜与Ac 2 O在回流下的反应通过消除反应生成了亚磺酸衍生物,如果氮是叔氮,但随后又被仲氮作为环亚磺酰胺捕获,则该亚磺酸衍生物随后会添加到生成的双键中。
