Abstract

The present invention relates to novel 1,2,4-dithiazolium iodide of the following general time (I), a process for its preparation, its use for controlling pests and novel starting materials.

Wherein R ¹ and R ² are as defined in the specification.

The novel 1,2,4-dithiazolium iodides of general formula (I) can be prepared by known methods, for example suitable 3-alkylthio-1,2,4-thithiazolium iodide, with suitable amines. It can be prepared by reaction with. The 3-alkylthio-1,2,4-dithiazolium iodide used here is likewise novel and can be prepared from 3-dimethylamino-1,2,4-dithiazoline-5-thione and alkyl iodide. Can be.
