Definitions
- the following invention relates to an electrochemical process for coupling anilines to biaryldiamines.
- aniline is used in this application as a generic term and thus also includes substituted anilines. Two identical or two different anilines can be coupled with each other.
- Previously used methods for the preparation of biaryldiamines use the detour of a sigmatropic rearrangement of diarylhydrazines (see: S.-E. Suh, l.-K. Park, B.-Y. Lim, C.-G. Cho, Eur. Org. Chem., 2011, 3, 455, H.-Y. Kim, W.-J. Lee, H.-M. Kang, C.-G. Cho, Org. Lett., 2007, 16, 3185, H. Kang, Y.-K. Lim, I.-J. Shin, H.-Y.
- Benzidine / semidine rearrangements are usually less selective and yield many carcinogenic by-products.
- the synthesis of the hydrazines is often carried out with the help of transition metal catalysts, which represents an additional cost factor.
- a major disadvantage of the above-mentioned methods for aniline-aniline cross-coupling is the frequent need for dry solvents and air exclusion. Furthermore, sometimes large amounts of partially toxic oxidizing agents are used. During the reaction often occur toxic by-products, which must be separated from the desired product consuming and expensive to dispose of. Due to scarcer raw materials and the increasing relevance of environmental protection, the price of such transformations is increasing. Especially when using multi-level sequences, a change of different solvents is necessary. Here also very toxic intermediates occur.
- Biaryldiamine be prepared without the organic oxidizing agent must be added, worked under exclusion of moisture or anaerobic reaction guides must be complied with.
- C- Coupling is a cost-effective and environmentally friendly alternative to previously existing multi-level classical organic synthesis routes opened.
