Dicyanoethylaryl derivatives and process for their preparation

摘要

The invention relates to new dicyanoethylaryl derivatives and to processes for their preparation. The compounds according to the invention can be used as redox indicators, such as, for example, for the detection of hydrogen peroxide with the aid of peroxidases or peroxidatively active substances. These redox indicators are futhermore suitable for the detection of peroxidases or peroxidatively active compounds, it also being possible to use other peroxides as oxidizing agents.
