Definitions
- the present invention relates to a novel process for the preparation of substituted azoles, in particular substituted 1H-tetrazoles and substituted 1H-triazoles.
- Azoles in particular the 5-substituted 1H-triazoles and -tetrazoles, are used inter alia as pharmaceutically active substances in medicine or are used, for example, in the protection of plants and technical materials as biocides.
- lithiation is the method of choice for derivatization of the 5-position, for example by halogens, the low temperature, the use of air-sensitive and less-expensive metallating reagents such as n-BuLi and especially the complete instability of the metallated intermediate at temperatures above -78 ° C are very disadvantageous.
