ELECTROCHEMICAL METHOD FOR PRODUCING DIPHENYLPHOSPHINE OXIDE, DIPHENYLPHOSPHINE OR PHOSPHINE AND THEIR DERIVATIVES

摘要

The invention relates to a method for producing diphenylphosphine oxide (DPPO) or its nucleus-substituted derivatives, diphenylphosphine (DPP) or its nucleus-substituted derivatives or phosphine (PP) or its nucleus-substituted derivatives, starting from triphenylphosphine oxide (TPPO) or the corresponding nucleus-substituted derivatives, or in the case of the production of DPP and PP, starting from triphenylphosphine (TPP) or the corresponding nucleus-substituted derivatives or DPPO. According to said method, the starting products are reduced electrochemically in the presence of ammonia or an amine.
